Question

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

Answer 1

x-intercept is 2
y-intercept is -4

Explanation:

the x-intercept is the value of `x` where the line of the equation crosses the x-axis; on the x-axis, `y=0`
so substituting `y=0` into `2x-y = 4`
gives
`2x-0=4` or `x=2`

Similarly, the y-intercept is the value of `y` where the line of the equation crosses the y-axis, `x=0`
so substituting `x=0` into `2x-y=4`
gives
`2(0) - y = 4` or `y=-4`
