Question

How to find the x and y-intercept given `y= -2x + 4`?

Answer 1

`y`-int `= 4`

`x`-int `= 2`

Explanation:

To find the `y`-intercept, you simply substitute in a `0` for `x`, which would give you the equation

`y = -2(0) + 4`

which then you simplify to get

`y = 4`

To find the `x`-intercept, you set `y` equal to `0`, which would give you the equation

`0 = -2x + 4`

then you move the `4` to the other side by subtracting

`-4 = -2x`

And finally, you divide both sides by `-2` to get

`x = 2`
