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
