Question

Write an equation for this trend line

Answer 1

`y = - (1)/(3) x + 8`

Explanation:

Using the formula for a straight line, y = mx + c

m refers to the gradient

c refers to the y-intercept

Gradient = rise ÷ run

= (8 - 7) ÷ (0 - 3)

=

`- (1)/(3)`

the equation for the line is

`y = - (1)/(3) x + 8`
