Question

Choose the equation of the line passing through the point (-2, 4) and perpendicular to y = -1/2x + 4.

y=2x+8
y=2x
y=-2x - 8
y= -2x

Answer 1

The given slope is ....... -1/2, burns, do you know the perpendicular slope?

Answer 2

No:/

Answer 3

take -1/2, flip it over and remove the negative sign, now we have the slope

2/1 or 2

y = 2x + b

It is either A) or B)

Answer 4

Ohh okay that makes sense. thank you!

Answer 5

y=mx+b , m=2 , (-2,4)

4=2(-2)+b
4=-4 +b
8=b

y=2x+8

it's A
