To start out, you'll want to get the slope of this line. The slope of the line between two points is equal to the difference in their y values divided by the difference in their x values: \[m=\frac{ \Delta y }{ \Delta x }=\frac{ y_1 - y_2 }{ x_1 - x_2 }\]

ok then plug into the point slope formula.

Right. Once you get the slope, you can plug into the equation: \[y-y_1=m(x-x_1)\]Where m is the slope of the line, and x_1,y_1 are the coordinates of any point on the line.
