How do you find the slope and intercept of 4x+8y = -64 ? Algebra Graphs of Linear Equations and Functions Slope-Intercept Form 1 Answer SagarStudy Jan 12, 2016 If Ax+By+C=0 Then Slope=-A/B, x-intercept=-C/A and y-intercept=-C/B. 4x+8y=-64 implies 4x+8y+64=0 implies x+2y+16=0 Here A=1, B=2 and C=16 implies Slope=-1/2, x-intercept=-16/1=-16 and y-intercept=-16/2=-8 implies Slope=-1/2, x-intercept=-16 and y-intercept=-8 Answer link Related questions What is Slope-Intercept Form?
