Question

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

y = -2x - 7

y = -2x +5

y = 2x + 5

y = 2x - 7

Answer 1

slope is negative reciprocal
m = -2

-1 = -2(-3) +b
-7 = b

y = -2x - 7
y = -(2x + 7)

Answer 2

So it would be the last option cause of the negative sign in front of the parenthesis ?

Answer 3

Answer 4

no it's the first option. The way of writing it with the parentheses is just the simplified form. The negative sign is distributed to both terms within the parentheses
