Question

slope intercept form of a line parellel to y=2x-7 passing through (-2,1)

Answer 1

wats the question?

Answer 2

find the slope intercept form of a line parallel to y=2x-7 and passing through (-2,1)

Answer 3

can anyone help me

Answer 4

slope intercept form is y=mx+b

Answer 5

a parallel line will have the same slope of 2. insert the x & y into the equation

Answer 6

I need the parallel line to the line

Answer 7

1=2(-2)+b
1=-4+b solve for b
5=b

now plug the slope and b into the slope intercept form of the equation

Answer 8

So we know that that the slop of the new equation has to be the same slope as your original equation which is "2"

plug your new slope and the value of the points in this equation:

(y+b) = m(x+a) where "a" and "b" is where your points have to pass through (-2,1) and your m = 2

Answer 9

slope of the given line=2
eq. of any line through (-2,1) and slope m is
y-1=m(x+2)
here m=2
solve and write in the form y=mx+b

Answer 10

so it would be (0,5)?

Answer 11

That's the y-intercept. The equation is: y=2x+5

Answer 12

so the parallel line would be up 2 over 5?

Answer 13

you start at (0,5) and move up 2, right 1 By extending the line, it should pass through the given point (1,-2) and be parallel to the given line.

Answer 14

thank you so much

Answer 15

You're welcome

Answer 16

I have another couple questions can you still help me

Answer 17

sure

Answer 18

how would I graph that

Answer 19

my graph only goes to 5

Answer 20

point on (0,5)--the y intercept. Then go up 2 and right 1. Graphing at least 3 points helps. Then extend the line

Answer 21

Keep plotting points

Answer 22

ok
