The equation for a line is y = mx + b. where m is the slope and b is the y intercept.
The slope is -1/3 (rise: 1, run: -3)
And the y-intercept is at -4.
So the equation for the line is:
y = -1/3x - 4
And we want all the y values BELOW the line of -1/3x - 4 as well as the values on the line because it’s not dotted. So instead of equals we write:
y <= -1/3x - 4
“Y is less than or equals to -1/3x - 4” where it includes the solutions on the line, as well as any solutions below it.
y <= -1/3x - 4 is the answer

What is the slope of the line passing through the points (8, 9) and (-2, 9)?
Answer:
Slope is 0
Step-by-step explanation:
First, find the difference in the x and y of each point by subtraction.
8 - (-2) = 10
9 - 9 = 0
Because the y value doesn't change in between these two points, that indicates the slope is 0

Andrew is hiking in a mountainous area of a state park. Use the given key features to sketch a graph.
y-intercept: Andrew starts at an elevation of 0 feet.
Extrema: Andrew's maximum elevation is 800 feet.
Increasing: At the start of the hike, Andrew's elevation increases steadily for 30 minutes. Then he stops to rest for 5 minutes.
Decreasing: Andrew hikes back to his starting point for the final 20 minutes.
Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.
A piece-wise function is a function that has multiple definitions, depending on the value of the input.
He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:
[tex]h(t) = \frac{800}{30}t, 0 \leq t < 30[/tex]
For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:
[tex]h(t) = 800, 30 \leq t < 35[/tex]
For the final 20 minutes, he descends 800 meters, at a linear rate, thus:
[tex]h(t) = 800 -\frac{800(t-35)}{20} = 800 - 40(t - 35), 35 \leq t \leq 55[/tex]
Using these definitions, the graph is sketched at the end of this answer.

x + 5 = x − 13
Let's solve your equation step-by-step.
x + 5 = x − 13
Step 1: Subtract x from both sides.
x + 5 − x = x − 13 − x
5 = − 13
Step 2: Subtract 5 from both sides.
5 − 5 = − 13 − 5
0 = − 18

There are no solutions.

A water tank currently contains 275 gallons of water. The amount of water in the tank will decrease at a constant rate of 15 gallons per week.
Which function can be used to find t, the total number of gallons of water in the tank after w weeks?
F t = 15w - 275
G t = -15w + 275
H t = 275w - 15
J t = -275w + 15
The function that can be used to find t, the total number of gallons of water in the tank after w weeks will be t = -15w + 275
The initial volume of water in the tank is 275 gallons
The amount of water in the tank decreases at a constant rate of 15 gallons per week.
t = total number of gallons water in the tank after weeks
w = number of weeks
Therefore, the following equation/theory can be establish
The initial gallon of water in the tank is 275 gallons that means we should have positive value of 275 in the equationThe gallon of water reduces by 15 gallons each week which means 15 gallons will be subtracted from the initial gallons of water each week. This means we have to find the product of -15 and w(number of weeks).The equation will be
t = 275 - 15w
or
t = -15w + 275
