Slope/Standard Form
I really can't do this to save my life and It's homework for tomorrow - I didn't know I had it. Help is much appreciated!!

it has to do with slope intercept and standard form

slope intercept form is :y=mx+b
standard form is ax+by=c (no decimals or fractions)

point,slope

m=2,(-4,2)
m=0,(2,-3)

two points

(0,2)(4,-2)
(-8,6)(-13,1)
(-4,5)(4,5)
(2,1)(-1,0)
(6,-1)(-1,6)
(3,4)(5,6)

Write the line in STANDARD form

y=2x-9
y=1/2x+2
(-8,3)m=2
(-6,-7)m=-1
(1,3)m=1/2
(-2,-4)m=3/4
(9,-2)(-3,2)
(4,-7)(5,-1)
(0,4)(2,3)
(-2,3)(4,-2)

Working must be shown.

MUCH THANKS TO WHOEVER CAN HELP.

point,slope

m=2,(-4,2)
m=0,(2,-3)

use the point-slope form ... $y - y_1 = m(x - x_1)$

two points

(0,2)(4,-2)
(-8,6)(-13,1)
(-4,5)(4,5)
(2,1)(-1,0)
(6,-1)(-1,6)
(3,4)(5,6)

find the slope ... $m = \frac{y_2-y_1}{x_2-x_1}$ , then use the point-slope form.
