Question

Find an equation for the line through (-8,3) and perpendicular to y=1/2x-4

Answer 1

Any idea?

Answer 2

no

Answer 3

What is the slope of y = (1/2) x -4?

Answer 4

um 1/2?

Answer 5

yup, now the required line is perpendicular with this line, hence, its slope is.....?

Answer 6

-1/2

Answer 7

-2/1=-2, not -1/2, got it?

Answer 8

Now, what is the formula of the line (slope formula)

Answer 9

so the answer would come out to what?

Answer 10

You need steps. So far, you have the slope of the required line, that is -2
you have a given point (-8,3)
All you need is the formula to plug them in. What is it?

Answer 11

idk the formula?
