What is the x intercept of 1/3x+y=-15

1/3 is going to be your answer

To find the x-intercept, substitute in 00 for yy and solve for xx. (0) - 3 x = - 15 0 - 3 ⁢x = - 15 Subtract 3x 3⁢x from 00 to get - 3 x - 3 ⁢x. - 3 x = - 15 - 3 ⁢x = - 15 Divide each term by - 3 - 3 and simplify. Tap for more steps ... x=5 x=5 To find the y-intercept, substitute in 00 for xx and solve for yy. y - 3 ⋅0 = - 15 y - 3 ⋅0 = - 15 Simplify the left side. Tap for more steps ... y = - 15 y = - 15 These are the xx and yy intercepts of the equation y - 3 x = - 15 y - 3 ⁢x = - 15. x-intercept: (5,0) 5,0 y-intercept: (0, - 15)
