You can put this solution on YOUR website!
5x%2B7y=32
8x%2B6y=46first off id reduce this equation to 4x%2B3y=23


5x%2B7y=32multiply by 4
4x%2B3y=23multiply by 5


20x%2B28y=128
20x%2B15y=115subtract equations


0%2B13y=13
y=1


5x%2B7%281%29=32
5x=32-7
5x=25
x=5


point (5,1) is intersection


5x%2B7y=32 ---> y=%28-5%2F7%29x%2B%2832%2F7%29 m=-5/7 y-int= 32/7 graph line
4x%2B3y=23 ---> y=%28-4%2F3%29x%2B%2823%2F4%29 m=-4/3 y-int= 23/4 graph line
