In order to write the equation of the line passing through the point (-2, 2) that is perpendicular to the line y = 2x + 3 , we must then find the perpendicular slope. What is the slope of any line perpendicular to line y = 2x + 3 ?

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
