The slope is change in "Y" divided by the change in "x" 1-(-3)/2-(-1) = 4/3
Standard Form y-y1=m(x-x1) y-(-3)=4/3(x-(-1) y+3=4/3x+4/3 y=4/3x-5/3
Rewrite in standard form -4/3x+y=-5/3 Can't have fractions so multiply by 3 to get rid of the denominator -4x+3y=5 Divide by -1 to get rid of the negative sign
