Then the slope, m, = the coefficient of x ================================================= 4x+8y=12 y=2x+10 -------------- Solve for y 4x+8y=12x 8y = 8x y = x Slope = 1 ----- y=2x+10 Slope = 2 If the slopes are equal, they're parallel. If the slopes are negative inverses, they're perpendicular. These 2 are: Neither ----------------- Do the others the same way. y=3x+2 5x+2y=20 y=3x+2 y=3/1x+15
