Name: Ke Date: Period: HW: Graphing Linear Equations Using Intercepts Use the graph to find the x-intercept and y-intercept of the following lines: 1. 5 4 x-intercept: (2,0) y-intercept: (0,3) 2 0 -4 2 3 45 2. 6 5 x-intercept: (-2.0) y-intercept: (0,4) 3 2 1- -10 2 3 3. 32 0 -2 x-intercept: (-4,0) y-intercept: (0,-1) 21 1 2 3 4 5 3 Find the x-intercepts and the y-intercepts of the following linear equations. You must write your final answer as an ordered pair. 4. 12x - 20y = 60 overline (12x - 20) * (0) = 60 (1Lx)/12 = 60/12 x = 5 (5,0) y-int n(0) - 20y = 60 (- 20y)/- 20 = 60/- 20 y = - 3 0,-3) 5. y = - 6 + 3x xint 0 = - 6 + 3x 6/3 = (3x)/3 x = 2 (2,0) Y-int y = - 6 + 3(0) y = - 6 (0, - 6) Find the x-intercept and y-intercept of the linear equation. Then, graph the equation using the intercepts. Label the intercepts. 6. 2x + 4y = 16 x-int 2x + 4(0) = 16 (2x)/2 = 16/2 x = 8 (8,0) y-int z(0) + 4y = 16 (4y)/4 = 16/4 y = 4 (0,4) 8. - 6x + 8y = 24 x 6x + 8(0) = 24 (- l * 0x)/- 6 = 24/(- l * 0) x = - 4 (-4,0) y-int - 6(0) + 8y = 24 (8y)/8 = 24/8 Y = 3 (0,3)
