Help, quick! What is the slope-intercept form of the function that contains the point (3, 4) and has a slope of 2? y = ___ x + ___

OpenStudy (igreen):

y = mx + b Where m = slope, so where does the 2 go?

OpenStudy (anonymous):

y=2x+__?

OpenStudy (anonymous):

Is that right?

OpenStudy (igreen):

Yep, and b is the y-intercept.

OpenStudy (anonymous):

So, 4?

OpenStudy (igreen):

The y-intercept here is -2.

OpenStudy (igreen):

So our final answer is..?

OpenStudy (anonymous):

Ah, okay, so it would be y=2x+-2?

OpenStudy (anonymous):

But, how did you come up with (-2) as a y intercept?

OpenStudy (anonymous):

Would it not be 4?

OpenStudy (anonymous):

Never you mind. Thank you for all your help.

OpenStudy (igreen):

y=2x+-2 is correct.
