Which of the following graphs represents the equation above
y= 1/3x - 3

Graph y because your y intercept is equal to -3 so that’s where you would start. Then your slope is equal to rise over run so you would go up 1 unit and right 3 since it’s positive

step-by-step explanation:

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.
