Question

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

Answer 1

Answer:

-1.5

Step-by-step explanation:

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

$\frac{y2 - y1}{x2 - x1}$

Substituting in, we get:

$\frac{5 - ( - 4)}{ - 2 - 4}$

Which simplifies to:

$\frac{9}{ - 6} = \frac{3}{ - 2} = - \frac{3}{2} = - 1.5$
