Answer #1

a. y= 4x-3, just plug what you know into slope intercept form. (y=mx+b) b. y= -x+7, use your slope for the equation, then plug the point into point-slope form (y-y1=m*(x-x1) Then, just fill it in. c. y= -x+2, Find slope by taking the points and doing y2-y1 over x2-x1. Then, find the y- intercept by using one of the coordinate pairs and putting it into point-slope form. Don’t forget to plug your slope into ‘m.’ Then, just fill it in.

Answer #2

you can fun mail me if you need more help =)

Answer #3

a) y=4x-3 b) y=-1x+__ (x,y) (2,-9) y=-1(2)-9 y=-2x-9
