Answer 1

Determine which system below will produce infinitely many solutions.

-4x + 6y = 20
4x - 3y = -2
-2x + 4y = 18
4x - 8y = -36
3x - 2y = 5
-6x - 4y = -10
5x - 3y = 12
15x - 9y = 24

Answer 2

Equation of a line
y = mx+b is a slope intercept form
also Ax+By=C is a STandard form of a line

if we let x be 0 or 1 or 2 or so on y will equal the corresponding y value
we can do this to infinity.

look at the color coded graph of the the line equations you gave.
