Question

On the graph of the equation 6x - y = -1, what is the value of the y-intercept?

Choose one answer.

A. -1
 

B. 1
 

C. -6
 

D. 6

Answer 1

First put in the equation in slope intercept form, where y=mx + b

 

m = slope

b = y intercept

 

In the equation, solving for y we can add the y to the other side of the equal sign so

 

6x = y-1

 

Then add 1 to both sides allowing us to read the equation in slope intercept form where the new equation is

 

y = 6x + 1

 

Since b is the y intercept, the y intercept is 1.

 

Therefore B is the correct answer.
