Question 1032493: I have been given the following equation: x-y=7, x+5y=-5
Without using technology, graph each equation and hence solve the system.
Can you please help me solve this answer by showing the process? I am stuck. Thank you very much for considering my request.

You can put this solution on YOUR website!
Find any two points for each equation, plot the points, draw each line.
Look at and read the intersection point.

Another way is put each equation into slopeintercept form and plot the necessary points and draw the lines.
y=mx+b, slope m, intercept point (0,b).

Each line:
-
-y=-x%2B7
y=x-7
-
5y=-x-5
y=-x%2F5-1
-
Identify each slope and intercept, and make the graphs on the same coordinate plane.
