Step-by-step explanation:
If the equation for a line in y-intercept form is:
![y=mx+b](/tpl/images/0244/1558/904ac.png)
Where m=slope, and b=y-intercept, then you just compare with your parameters.
If m=3 and b=7, then the correct answer is ![y=3x+7](/tpl/images/0244/1558/a6983.png)
Please let me know if you have any other questions about this or anything else.
Thanks!
