Which equation represents the line through (4, -6) and (0, 2)?
Ill give brainlest to first RIGHT ANSWER.
Answer:
[tex]y=-2x+2[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0).
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (4, -6) and (0, 2):
[tex]m=\displaystyle\frac{-6-2}{4-0}\\\\m=\displaystyle\frac{-8}{4}\\\\m=-2[/tex]
Therefore, the slope of the line is -2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-2x+b[/tex]
2) Determine the y-intercept (b)
The y-intercept occurs when x=0. We are given that (0,2) falls on the line, so therefore, 2 is the y-intercept. Plug this into [tex]y=-2x+b[/tex]:
[tex]y=-2x+2[/tex]
I hope this helps!
Answer:
y = - 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (0, 2 )
m = = = = - 2
The line crosses the x- axis at (0, 2 ) ⇒ c = 2
y = - 2x + 2 ← equation of line

A square room has an area of 14,400 square
inches. What is the length of a side of the
room in inches?
Answer:
120 inches
Step-by-step explanation:
The area for formula is [tex]A=l*w[/tex], where A is area, l is the length, and w is the width.
However, since it's square room, you can just multiply the length times itself. This makes the formula [tex]A=l^{2}[/tex].
Now you can substitute 14,400 for A, since that's the area. this brings us to [tex]14400=l^{2}[/tex]. To solve the equation, just find the square root of both sides.
The square root of [tex]l^{2}[/tex] is l.
The square root of 14400 is 120. (I used a calculator for this.)
(BTW, a square root is the number that can be squared to get to a number. For example, the square root of 25 is 5, because 5 times 5 is 25. The square root of 14400 is 120, because 120 times 120 is 14400.)
Answer:
120 INCHES IS THE SIZE OF THE ROOM.
Step-by-step explanation:
120 is the answer because A(Area) = L(Length) x W(Width)
The area for formula is , where A is area, l is the length, and w is the width.
However, since it's square room, you can just multiply the length times itself. This makes the formula .
Now you can substitute 14,400 for A, since that's the area. this brings us to . To solve the equation, just find the square root of both sides.
The square root of is l.
The square root of 14400 is 120. (I used a calculator for this.)
(BTW, a square root is the number that can be squared to get to a number. For example, the square root of 25 is 5, because 5 times 5 is 25. The square root of 14400 is 120, because 120 times 120 is 14400.)

Sarah babysits her neighbor's son to make money. Her earnings can be represented by the equation
M = 9h
where M is the money she earns and h is the hours she babysits.
Samara babysits her cousin to make money. Her earnings can be represented by the graph.
Answer:
27
Step-by-step explanation:
Due to the fact that M=9h you must do M=9(3).
M stands for the amount of money that Sarah will receive for babysitting. H stands for the amount of hours Sarah is babysitting. $9 is the amount of money Sarah makes per hour.
You get the number 3 by seeing where the blue dot is and scrolling down.
Therefore, M=9(3)
The answer is 27

Caroline has a discount card that gives her 4% off the purchase of each pizza.If p is the cost of a regular pizza, how much does caroline pay for her pizza?
A. p - 0.4
B. 0.96p
C. p - 0.04
D. 1 - 0.04p
Answer:
C.
Step-by-step explanation:
When you transfer 4% into a decimal, it equals 0.04, and p is the cost of a regular pizza, so you subtract 0.04 from p!

write an expression to show the total volume of the two boxes i-ready
Answer:
The answer is 512 in³.
Step-by-step explanation:
The formula for the volume of the box is V = s³.
Since 8 is the side length, substitute s for 8 in the formula: V = 8³.
8³ is the same as 8×8×8, which is equal to 512.
Therefore, the answer is 512 in³.
Hope this helps!
The expression to show the total volume of the two boxes is 512 in.³
What is volume of cube?The volume of a cube is defined as the total number of cubic units occupied by the cube completely. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.
a) In the given figure, volume of bigger box is s³ and the volume of smaller box is 100 in.³
Total volume =s³+100
b) The volume of larger box has a side length of 8 inches
Now, s³
Where, s is edge, s=8
Volume =8³
= 512 in.³
Therefore, the expression to show the total volume of the two boxes is 512 in.³
