6

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 ( 0,0) & ( 3,18)

m=18- 0/3- 0

Subtract terms

m=18/3

Calculate quotient

m=6

The slope of the line that passes through the given points is 6.
