Graph a Linear Equation

Graph the linear equation 4x-2y=6

  1. Slope-intercept form (y=mx_b)
    • 4x-2y=6
    • -4x      -4x
    • \frac{-2y}{-2}=\frac{6-4x}{-2}
    • y=-3+2x
  2. Find points

 

x y
0 y=-3+2(0)=-3
1 y=-3+2(1)=-1
2 y=-3+2(2)=1
  1. Graph
y=2x-3
slope=2
y-intercept=-3
(0,-3)
Slope=\frac{rise}{run}=\frac{2}{1}
