Question

How do you find the intercepts of `y=-3-3x`?

Answer 1

`x= -1 and y = -3`

Explanation:

The intercepts are the points on the axes.

All points on the x-axis have a y-value = 0.
All points on the y-axis have an x-value = 0.

To find the y-intercept, make x = 0 and solve for y.

`y=-3-3x` becomes `y = -3 -3(0)`

`y = -3`

To find the x-intercept, make y = 0 and solve for x.

`y=-3-3x` becomes `0 = -3-3x`
`3x = -3`

`x = -1`
