Question

solve graphically the following equation 5x-4y+8=0 and 7x+6y-9=0

Answer 1

..........................

Answer 2

put x=0
5(0)-4y+8=0
-4y+8=0
-4y=-8
y=-8/-4
y=2
put x=1
5(1)-4y=-8
-4y=-8-5
-4y=-13
y=-13/-4
put x=2
5(2)-4y=-8
10-4y=-8
-4y=-8-10
-4y=-18
y=-18/-4
7x+6y=9
put x=0
0+6y=0
y=-6
put x=1
7+6y=9
+6y=9-7
6y=2
y=2/6
y=1/3
put x=2
14+6y=9
6y=9-14
6y=-5
y=-5/6
I hope this ans will help you
