4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4
4x + 5y = 20 5y = -4x + 20 y = (-4/5)x + 20/5 Now that the equation has been rewritten in standard form, the slope is the cofficient of x, -4/5 [or -0.8]
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
-4x + 5y = 10Add 4x to each side:5y = 4x + 10Divide each side by 5:y = 0.8x + 2The graph of this equation is a straight line with [ slope = 0.8 ] and [ y-intercept = 2 ].
