Question

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (-1, 2).

y = 2x + 4

y = - 2x + 2

y = - 1 over 2 x + 2

y = 2x - 1

Answer 1

I don't know what the line on the graph is :/

Answer 2

If i did I could solve

Answer 3

you don't even require the graph because you have a point and 4 choices

Answer 4

but lets do it by finding the equation of the line on the graph

Answer 5

can you choose any 2 points on that line ?

Answer 6

Ok thank you cuz I honestly do not know how to

Answer 7

(0,-1) and (-2,0)

Answer 8

yes!

Answer 9

know the slope formula, given 2 points ?

Answer 10

y2-y1/x2-x1

Answer 11

yes! you know everything :P :)

Answer 12

0--1/-2-0
1/-2

Answer 13

-1/2?

Answer 14

so we have the slope
yes, its -1/2
how will you find the slope of perpendicular line ?

Answer 15

negative reciprocal of the slope of the parallel line or line given

Answer 16

-1/(-1/2) ?

Answer 17

yes, which = ..?

Answer 18

2

Answer 19

correct!
m=2
point = -1,2
equation will be ?

Answer 20

2=2*-1+b
2=-2+b
4=b

y=2x+4 ?

Answer 21

sure it is :)
