Graph a line that contains the point (-7,-4) and has a slope of
2
3

y = 2/3x + 2/3

Step-by-step explanation:

just substitute every known value into the parent function on a linear function

y = mx +b

-4 = 2/3(-7) +b

now solve for b (the y-intercept)

-4 = -14/3 + b

-12/3 = -14/3 + b ( made it to same denominator)

2/3 = b

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.
