Question

Calculate the slope of a line perpendicular to these two lines y=-2x+3 and y=-2x+6

Answer 1

slope of a line perpendicular to these two lines = 1/2

Explanation:

y=-2x+3; y=-2x+6

Slope of these two line m1= -2

Slope of perpendicular lines m1 * m2 = -1

-2 * m2 = -1

m2 = -1/-2

m2 = 1/2
