what is the y intercept of y=-x

Question

I just need the y intercept if there is one

Answer 1

To find the y-intercept, we just need to find the answer when x = 0.

 

y = -(0)

y = 0

 

So the line crosses the y-intercept at (0, 0)

 

Answer 2

The general formula for a straight line is:

 

y = mx + b

 

Where:

• m = the slope of the line
• b = the y-intercept

 

Your equation is y = -x, which can be written in mx+b form as:

 

y = (-1)x + 0

 

Where m = -1 = the slope and b = 0 = the y-intercept.
