Question

What is the equation of a line that passes through (-6, 2) and has a slope of -1/2

Answer 1

(- 6, 2)....x = - 6 and y = 2
slope(m) = - 1/2

y = mx + b
now we sub...we have everything but b....can u find b

Answer 2

2 = -1/2(- 6) + b
now find b

Answer 3

ur answer will be y = -1/2x + (whatever u get for b)

Answer 4

the answers I have to choose from is
a. y= x/2-2
b. y=x/2-1
c. y=2x+1
d. y=-2x-1

Answer 5

First you could put it in point slope form that might be easier for you

Answer 6

Y-y1=m(x-x1) where y1 and x1 are the point they give you

Answer 7

So let's plug in the given information y-2=-1/2(x+6)

Answer 8

okay now how do I solve that?

Answer 9

Distribute the -1/2

Answer 10

First so -1/2 times x is -1/2x now what is -1/2 times 6

Answer 11

-3

Answer 12

Good so we have y-2=-1/2x-3

Answer 13

We need to have the y all by itself so what do you have to do?

Answer 14

add 2

Answer 15

Yep :)

Answer 16

So you get?

Answer 17

y=-1/2x-1

Answer 18

Yes :)

Answer 19

so my answer would be d. -2x-1?
