Question

What is the slope of the line containing (-2, 5) and (4,-4)?

A. 2
OB.
mle
O C. - /3/20
D. -2

Answer 1

-1.5

Explanation:

To work out the gradient of the line, we use this equation:

`(y2 - y1)/(x2 - x1)`

Substituting in, we get:

`(5 - ( - 4))/( - 2 - 4)`

Which simplifies to:

`(9)/( - 6) = (3)/( - 2) = - (3)/(2) = - 1.5`
