Question

What is the slope and y-intercept of the line `y=7x-3`?

Answer 1

`(0,-3)` is the y-intercept
slope is equal to `7`

Explanation:

`y=7x-3` is in the general form `y=mx+b` where m is the gradient or slope

So your slope is equal to `7`

The y-intercept can be found when `x=0`

`y=7(0)-3`

`y=-3` ie `(0,-3)`
