Question

How do you find the x and y intercept of `y=7x`?

Answer 1

0, 0

Explanation:

`x` intercepts occur on the `x` axis, where `y=0`. So to find them, you plug in `y=0` in to the equation and solve for `x`.

`0=7x`
`0=0` so the y intercept is at the origin, `(0,0)`

`y` intercepts occur when `x=0`
`:. y=7(0)`
`y=0`

`:.` the x and y intercepts of `y=7x` is `(0,0)`
