Find the x- and y- intercepts for the graph of the following equation.
5x + 3y = -30

Answer 1

To do this you just put 0 in for x to find the y and then after you found it go back to the problem and put 0 in for y to get the x

Answer 2

x=(-6,0) y=(0,-10)

Answer 3

To find the x-intercept, Let y = 0
5x + 3y = -30
5x + 3(0) = -30
5x = -30
-- ----
5 5

x = -6

(-6, 0)

To find the y-intercept, Let x = 0
5x + 3y = -30
5(0) + 3y = -30
3y = -30
--- ----
3 3

y = -10

(0, -10)
