You want to graph the equation 2x - 5y = 20. You decide to calculate the 2 intercepts. Type the value of the y-intercept as a point.

Question

Do not insert any spaces in your answer

Answer 1

Hi Caleb, the y-intercept point occurs when x is equal to zero. For the given line, 2x - 5y = 20, set x = 0, to find the y-intercept point.

 

0 - 5y = 20

 

Divide both sides by -5 gives:

 

y = -4.

 

The y-intercept point is: (0,-4)

Answer 2

Transform the equation into the slope/intercept form:

y=mx+b     (1)

 

The y-intercept occurs when x=0, so the answer is

0,b

 

where b comes from formula (1) above.
