Answer:
im guessing you're trying to find where the lines will meet at, so the lines will meet at (1,-1)
Explanation:
sadly it doesnt allow me to add in a photo but ill tell you a good enough explanation of what to draw, for y=3x+2 your line starts at 2 on the y axis and goes down (-3/1)
for y=3x-4 your line starts at -4 and go up by 3/1
hope this helped, not sure if you need anything more.
