Question

I really need help on this

Answer 1

I) I picked the first two points

To estimate the relationship between these variables, use the equation:

y = mx + b

where m is:

$\text{slope, m= }\frac{y2-y1}{x2\text{ - x1}}\text{ = }\frac{4100-5200}{82-97}=-220$

Thus, the equation is:

y = mx + b
