How do you find the x and y intercept of y=7x? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer TreeReader Aug 25, 2017 0, 0 Explanation: x intercepts occur on the x axis, where y=0. So to find them, you plug in y=0 in to the equation and solve for x. 0=7x 0=0 so the y intercept is at the origin, (0,0) y intercepts occur when x=0 :. y=7(0) y=0 :. the x and y intercepts of y=7x is (0,0) graph{7x [-2, 2, -5, 5]} Answer link Related questions What is the x and y Intercepts?
