Question

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

y = -2x - 7

y = -2x +5

y = 2x + 5

y = 2x - 7

Answer 1

perpendicular again remember is the negative reciprocal of the slope..so that of 1/2...is -2/1 or just -2 is your slope..

now use the point slope formula again

y - (-1) = -2(x - (-3))
y + 1 = -2(x+3)
y + 1 = -2x - 6
y = -2x - 7

check

-1 = -2(-3) - 7
-1 = 6 - 7
-1 = -1? Yes it does so it works :)
