Question

Find the slope of each line

Answer 1

• The slope is - 10.

=========================

Use two points on the graph to work out the slope.

The points are:

• (4, 5) and (5, - 5).

The slope formula:

• 
  `m=\cfrac{y_2-y_1}{x_2-x_1}`

Substitute and calculate:

• 
  `m=\cfrac{-5-5}{5-4}=\cfrac{-10}{1} =-10`
