Question

Which equation, when graphed with the given equation, will form a system that has an infinite number of solutions? A. y+1=3x B. y=-3x+1 C. y=3x+1 D. y-3x=-3

Answer 1

Answer: A

Explanation:

Answer 2

A ) y+1=3x

1) When there infinitely many solutions, the graph of the linear system is going to be one line overlapping the other.

2) So examining the options, and inserting on the Cartesian plane the following equation:

y+1= 3x

We'll have one line overlapping the other one because y= 3x -1 and y+1=3x are the same equation.

y+1=3x

y=3x-1

3) So the answer is A ) y+1=3x
