4.3 Using Intercepts to Graph Equations Using Intercepts to Graph Equations (4.3) x-intercept - x value where the graph crosses the x-axis y-intercept - ________________________ ____________ Find the x - intercept of the following. HINT: to find x-intercepts, substitute 0 in for y and solve for x. 1. 2x + 3y = 6 2. y = 2x + 20 Find the y - intercept of the following. HINT: to find y-intercepts, substitute 0 in for x and solve for y. 1. 2x + 3y = 6 2. y = 2x + 20 Find the x intercept and y intercept of 2x + y = 15 4.3 Using Intercepts to Graph Equations Graph the equation... 3.5x + 7y = 14 Find the intercepts by plugging in zero. To find the x-intercept, make y=0 To find the y-intercept, make x=0 y = 4x + 40
