SOLUTION: I understand how to find x and y intercepts except when it asks 4y=-12 I know that I should divide 4 into -12 to get the y intercept but how do I go about getting the x intercept?

Question 1006732: I understand how to find x and y intercepts except when it asks 4y=-12 I know that I should divide 4 into -12 to get the y intercept but how do I go about getting the x intercept? Do I make up numbers like -1, 0, and 1 to find the x intercept? I'm totally confused with this. Please help.

If that one is a multi-variable linear equation, then there are no restrictions on the other variables, or if for just two dimensions, no restriction on x.

4y=-12
4y%2F4=-12%2F4
y=-3-----------this is just a horizontal line at y=-3, and for all values of x. This had NO x-axis intercept.
