WILL GIVE BRAINLIEST! what are the values of a and b so the system of equations has infinitely many solutions?
y= -1/2x+b
y= ax + 15

a: -1/2

b: 15

Step-by-step explanation:

A system that has infinite solutions is the same line on top of itself.

Hope that helps

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
