9.
Through (-2,3) and (0,5)
10.
Through (1,7) and (3, -3)

7. y = 3x − 4

8. y = -5x + 27

9. y = x + 5

10. y = -5x + 12

Step-by-step explanation:

if you're given two points, find the slope first. To find slope the formula is...

(y₂ - y₁)/(x₂ - x₁).

For example, if you look at 7, you find the slope by subtracting one y value with the other, which would be 11 - 5.

Then, divide this by the second x value with the other, which would be 5 - 3. you get the slope, which is 3.

Then, plug in one of the points into the equation you have now, which is y = 3x + b (since you don't know b).

So you would get 5 = 3(3) + b, subtract, and you can find b, and make an equation.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

your answer is 125y5
