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)

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

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