For any equation ax+by+c = 0, slope is .X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -3/4 = -0.75.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -3/1 = -3.Slope is -4/1 = -4. Equation in slope-intercept form: y=-4*x+-3.

2(x - 5) - 3(4x + 4)
use the distributive property
do 2 times x minus 2 times 5 minus -3 times 4x plus -3 times 4
you do the -3 because the "-" sign makes it negative

2x-10-12x+(-12)
combine like terms
-10x-10+-12
combine like terms
-10x-22
