If you want to find the equation of line with a given a slope of which goes through the point ( , ), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
where is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
Plug in , , and (these values are given)
Rewrite as
Distribute
Multiply and to get
Subtract 3 from both sides to isolate y
Combine like terms and to get
------------------------------------------------------------------------------------------------------------
Answer:
So the equation of the line with a slope of which goes through the point ( , ) is:
which is now in form where the slope is and the y-intercept is
Notice if we graph the equation and plot the point ( , ), we get (note: if you need help with graphing, check out this solver)
Graph of through the point ( , )
and we can see that the point lies on the line. Since we know the equation has a slope of and goes through the point ( , ), this verifies our answer.

--------------------------
Use the slope-intercept form, y = mx+b where m is the slope
and b is the y-intercept:
Your Problem:
y = 5x-3
