Question

Graph the equation. y = 4x – 3

Answer 1

What's the y-intercept of this equation? :)

Answer 2

4?

Answer 3

It's in the slope-intercept form y=mx+b where m is the slope and b is the y-intercept. So the y-intercept is -3. :) Knowing this, which answers can we cross out?

Answer 4

C. and D.?

Answer 5

We can cross out C, yes. However, D has a y-intercept of -3, so let's leave that one for now. There is one other option we can cross out that doesn't have a y-intercept of -3. Which one is that? :)

Answer 6

B.

Answer 7

You got it. :) Now we have A and D. The slope is positive 4. A positive slope means the line will go down on the left and up on the right. So your answer is...? :P

Answer 8

d.!

Answer 9
