Question

Choose the equation of the line passing through the point (-3, -1) and perpendicular to y = 1/2 x + 3.

y = -2x - 7

y = -2x +5

y = 2x + 5

y = 2x - 7

Answer 1

the perpendicular line has a slope of m = -2

this is because the the slope of the line times the slope of the perpendicular must = -1

1/2 x -2 = -1

so you line is

y = -2x + b

to find b substitute x = -3 and y = -1 into the equation to find b... then you'll have your straight line
