determine the slope of the line (0, 3.2) and (-4, 1.5)

Question

Need to make sure I have the correct answer

Answer 1

in order to compute the slope you want to take

m = (y2 - y1) / (x2 - x1)

on this one we have

(1.5 - 3.2) / (-4 - 0)

= -1.7 / -4

=0.425

meaning that the slope here is m = 0.425

Answer 2

Hi Cayce,

 

To determine the slope of the line passing through two points use the formula for slope.

 

The following graph shows the results of two different ways to do the calculation.

The graph also shows the line passing through those points (and respective equations) using point-slope.
