The way that you find this problem is to first find the slope, and then input one of your points into your equation to find b.
The slope-intercept form of a line is:
, where m is the slope and b is the y-intercept.
To find the slope, you must use the following equation:
In this equation, this would be equivalent to:
which, when simplified, is 
. This is your slope.
To find the Y-intercept, you just plug all variables that you currently have solved for into the equation. You may use either point for the x and y variables, but you must use for the m term.
leads to 
which leads to 
. You have now solved for the y-intercept and aare ready to form your final equation.
The final equation is:
