Find the y-intercept, if there is one of: y=2x-3

OpenStudy (lena772):

y+3=2x?

OpenStudy (ranga):

You don't have to rewrite the equation at all. Just compare y = mx + b to y = 2x - 3. What is b? b is the y intercept. Another way to find the y intercept is put x = 0 and evaluate y.

OpenStudy (ranga):

If you put x = 0 in y = 2x - 3 what do you get for y?

OpenStudy (lena772):

y=-3

OpenStudy (ranga):

yes, -3 is the y intercept.
