Hi Danielle;
Begin with establishing slope...
m=(y-y1)/(x-x1)
For this, you will use both points.
Then, use only one point in the point-slope formula...
y-y1=m(x-x1)
I would apply the provided coordinate to the (x1,y1) components of the equation, rather than (x,y).
This equation will expand into slope-intercept form...
y=mx+b, m is the slope, b is the value of y when x=0, also known as the y-intercept.
Then, use the other point to verify the results.

You can randomly select points. However, that would be the hard way. The easiest is to select...
y-intercept, (0,y)
x-intercept, (x,0)
Concerning the y-intercept, bear in mind the fact that...
y=mx+b
b is such value of y of the point (0,y).
Let me know how you do.
