What do you need to do to make the correlation coefficient to be 0.5? And describe where the points are in relation to the line.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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.

y-y1=m(x-x1)

y-1=1(x-8)
