Question

The line of best fit for the graph above has the equation

y = -3x + 2. What value does the line predict when x = 9?

Answer 1

y = -25

Explanation:

The equation of line is given as :

y = -3x + 2

We need to find the value when x = 9.

Put x = 9 in the given equation. So,

y = -3(9)+ 2

= -27+2

= -25

So, the value of line is equal to -25.
