Question

Which of these equations has a y-intercept of 4?

A. y=x+4
B. y=x-4
C. y=4x
D. y+4=x

Answer 1

A

Explanation:

Since A is already in slope intercept form, we know that the b value is already in the correct place.

y = mx + b

In slope intercept form, the b is the y int.

Thank me later :)

Answer 2

Option A, y = x + 4

Explanation:

Step 1: Determine which option is correct

y = mx + b

m is the slope while b is the y-int

So... the equation with a 4 for b should be the correct answer.

Option A states the following: y = x + 4

This shows that the y-int is 4 and the slope is 1. So, this answer is correct.

Answer: Option A, y = x + 4
