Graph the linear equation. Then use the graph to estimate how many solutions the equations share.

1. 3y+4x=16

2x-y=18

2. y=-5x+6

10x+2y=12

1. 3y+4x=16

2x-y=18

Here's the graph of this one :https://www.desmos.com/calculator/ca7j4iemr4

2. y = -5x+6

10x+2y=12

Rearranging the first equation as 5x + y = 6

Multiplying by 2 on both sides

10x + 2y = 12 produces the same equation as the second one.....thus, these are the same line....so we will have infinite solutions
