Question 678819: I'm really stuck on this problem on my math homework. Thanks to anyone who helps! :)
A line on a coordinate plane has a y-intercept of negative -3 and goes through the point (2, 3). What is the line in the form y =mx + b?

You can put this solution on YOUR website!
y intercept is (0,-3)
...
Using also point (2,3), find the slope.

%28-3-3%29%2F%280-2%29+=+-6%2F-2+=+3
...
Using slope of 3, and either point, apply the slope-point formula
y - -3 = 3(x-0)
y + 3 = 3x
