First of all, you know that the x-intercept is 77 and the y-intercept is -6−6. In addition, by knowing this you can now figure out the equation of this line.
Furthermore, you now have two points you can work with (7,07,0 and 0,-60,−6). To add on, as your next step you will have to find the slope of the line which you can figure out by finding the rise over the run;(y^2-y^1)/(x^2-x^1)y2−y1x2−x1
Therefore, your y^2y2 would be 00 (which comes from the point 7,07,0) and your y^1y1 would be -6−6 (which comes from the point 0, -60,−6), thus when you subtract -6−6 from 00 you get a result of +6+6.
In addition, your x^2x2 would be 77 (which comes from the point 7,07,0) and your x^1x1 would be 00 (which come from the point 0,-60,−6), thus when you subtract 00 from 77 you get 77.
So, now that you have the numbers 66 and 77 all you have to do is divide them so that you get the fraction 6/767. In continuation, from this you can now write the equation of the line which would be 6/7x67x(the slope) minus 66 (which is the y-intercept).
This is a demonstration of how the graph would look like;
graph{6/7x-6 [-7.65, 12.35, -8.15, 1.85]}
6/7x-667x−6
