Well we would need to see some type of graph in order to help you find the slope.
One solution
The two (or more) equations would only intersect once
No solution
Lines never intersect
The lines are parallel
Infinite solutions
The lines are the exact same
That’s all the characteristics I know
9(x-5)=5+(9x+5x)
9x-45=5+14x
9x-14x=45+5
-5x=50
X=50/-5
X=-10
The intercept would be 5 Y if you acually solve that equation
C. Line crosses y-axis at 1. Line goes 1 unit down and 4 units across.
