Question

Find the slope of line passing through the points (4,8) and (6, -2).
A. 1/5
B. 5
C. -1/5
D. -5

Answer 1

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



m = ( -2-8)/(6-4)



m = -10/2



m = -5



So the slope of the line that passes through the two points is -5

Answer 2

You use the slope formula:
\[m=\frac{y _{1}-y _{2}}{x _{1}-x_{2}}\]
and plug in the points given to you:
\[m=\frac{8-(-2)}{4-6}\]
Simplify and get that
\[m=\frac{10}{-2} or -5\]
So your answer is D :)
