Question

Find the y-intercept of the following line. y = - 3x - 4 Give your answer as an ordered pair (a,b).

Answer 1

The y-intercept is -4.

Explanation:

Our task is to find the y-intercept of the line
`\sf{y=-3x-4}`.

The format of this line is slope-intercept. That's good news! Finding the y-intercept is a piece of cake.

All we need to do is spot the constant term. That constant term will be the y-intercept.

The constant term is -4. Therefore, that's our y-intercept.

We can write this as an ordered pair: (0,b).

The value of b is -4, so the y-intercept is (0,-4).

Answer 2

Answer: (0,-4)

Explanation:

This equation is written in slope intercept form meaning that y = mx+b

where m is your slope and b is your y-intercept.

So that means we already have our y-intercept which is -4. To give our answer as an ordered pair it will be (0,-4).
