Answer:
y=-4x-3
Step-by-step explanation:
Hi there!
We are given the following two points: (-2,5) and (-1,1)
We want to write the equation of the line that passes through these two lines in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
First, let's find the slope
The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion
[tex]x_1=-2\\y_1=5\\x_2=-1\\y_2=1[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{1-5}{-1--2}[/tex]
Simplify
m=[tex]\frac{1-5}{-1+2}[/tex]
Subtract
m=[tex]\frac{-4}{1}[/tex]
Divide
m=-4
Now substitute -4 as m into the equation:
y=-4x+b
Now we need to find b
As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.
Taking (-2,5) for example:
Substitute -2 as x and 5 as y:
5=-4(-2)+b
Multiply
5=8+b
Subtract 8 from both sides
-3=b
Substitute -3 as b.
y=-4x-3
Hope this helps!

Explanation:
9x + 4y = 282x + 4y = 0
Make "x" subject in equation 2
2x + 4y = 02x = -4yx = -2yInsert this in equation 1
9(-2y) + 4y = 28-18y + 4y = 28-14y = 28y = -2Find for x
x = -2yx = -2(-2)x = 4Kassie and Luke timed each other during swimming practice. The speed at which swims is represented by the equation d = 1. 22t, where d is the number of meters she swims in t seconds. The speed at which Luke swims is represented in the table.
This means that a graph of Kassie speed given by the function d = 1.22t would have a slope of 1.22 m/s.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.

Step-by-step explanation:
just apply the formula you can find immediately on the internet.
that is much faster than putting such a calculation question in here.
the area of a circle is
pi×r²
with r being the radius.
so, in our case we have
pi × 3² = pi × 9 = 28.27433388... ft²

Annabelle measured her bedroom as 11 ft times 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply. there are 12 inches in every foot. the length and width will change by a factor of 1.2 times 10 superscript 1. the length and width will change by a factor of 1.2 times 10 superscript 0. the area will change by a factor of (1.2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 1.44 times 10 superscript 2 baseline = 144, since area is length times width. the area will change by a factor of 2 (1.2 times 10 superscript 1 baseline) = (2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 2.4 times 10 superscript 2 baseline = 240, since both the length and width increase by that factor.
There are 12 inches in every foot and the area will be increased by 144 factors.
We know that the feet and inches are the units of length. One foot is 12 inches.
The length and the breadth are given as 11 feet and 13 feet.
The area of the bedroom is 143 square feet.
We know that 1ft = 12 in
So, The length would become 11 feet to 132 inches.
The breadth would become 13 feet to 156 inches.
What is the formula for the rectangle?The area of the rectangle = length × Width
Therefore, the area of the rectangle = 132 × 156
Since area of the rectangle= 20592 in .sq
The area of the bedroom increased by 144 factors.
