Question

The Question is: Write an equation for the line that is parallel to the given line and passes through the given point. Write your equation in slope-intercept form. y = 4x - 3; (-3,12). I don't want the answer, I want to know how to figure it out. Any help is appreciated :)

Answer 1

tell me for two lines if the slopes are parallel what would their slopes be in relation to each other?

Answer 2

The reciprocal right?

Answer 3

no negative reciprocal is for lines perpendicular to each other

Answer 4

the slope would be the same for lines that are parallel to each other

Answer 5

first of all from what they give u tell me what is the slope?

Answer 6

According to the given equation it would be 4/1.

Answer 7

yes and so now u have a m=4 and the pt given (-3,12) which represents (x,y)
using y=mx+b solve for b

Answer 8

nice explanation...ngott :)

Answer 9

The y intercept would be 24 I think.

Answer 10

assuming ur algebra is right now u have everything u need to write the equation in slope intercept form
y=4x+24

Answer 11

That really helped :). I only have one more problem on the worksheet like this one. I think I can do it though :P

Answer 12

y = mx + b (m = 4, x = -3, y = 12)
12 = 4(-3) + b
12 = -12 + b
12 + 12 = b
24 = b
yes...your equation is : y = 4x + 24

Answer 13

if you were looking for the slope intercept form, you could use y = mx + b to solve it, or you could use y - y1 = m(x - x1) and then put it in y = mx + b form.
But if it specifically asks for slope intercept form, would just use y - y1 = m(x - x1)

Answer 14

oops...specifically asks for point slope form, you would use y - y1 = m(x - x1)

Answer 15

@Hardcorefr3k im sorry but @texaschic101 is correct
