# How do you find the slope of the secant lines of #f(x) = -3x + 2 # through the points: (-4,(f(-4)) and (1,f(1))?

#### Explanation:

Find the points'

#f(-4)=-3(-4)+2=12+2=14#

#f(1)=-3(1)+2=-3+2=-1#

The two points on the secant line are

The slope

#m=(Deltay)/(Deltax)=(14-(-1))/(-4-1)=15/(-5)=-3#

This should make sense, since

Since the secant line is identical to
