2

Practice makes perfect

We can calculate the slope by substituting the given points into the Slope Formula.

m=y_2-y_1/x_2-x_1

SubstitutePoints

Substitute ( 0,-4) & ( 2,0)

m=0-( -4)/2- 0

Add and subtract terms

a-(- b)=a+b

m=0+4/2-0

Add and subtract terms

m=4/2

Calculate quotient

m=2

The slope of the line that passes through the given points is 2.
