y = 7x - 17
Step-by-step explanation:
If you graph the coordinate (3,4) and then apply the slope (7 up / 1 down) , you will end up passing through the point (0,-17) on the y line. The point the line passes on the y line would be the y intercept.
Once you have all the necessary information, you put it into a y=mx+b form. m being the rate or slope, and b being the y-intercept.
