The slope is #5#

To find the slope using two points, divide the difference of the y-coordinates by the difference of the x-coordinates

#(y_2-y_1)/(x_2-x_1)#

In this case, #y_2# would be 21, #y_1# would be 1, #x_2# would be 2, and #x_1# would be -2

#(21-1)/(2-(-2))#

#20/(2+2)#

#20/4#

#5 rarr# This is the slope
