Question

How do you find the x and y intercepts for `x + 2y = 4`?

Answer 1

Substitute in zero for x and then for y.

Explanation:

The x intercept occurs when `y=0` and the y intercept occurs when `x=0`
Therefore the x-intercept can be found from `x +2*0 = 4`
`x=4`
The y-intercept is found from `0 + 2y = 4`
`y=2`
