Question

Which equation has the solution of (3, 0) and an undefined slope
y=4
x=3
y=4x
y=4x+3

Answer 1

The answer is x = 3, because x = 3 has an undefined slope (m = 0 or is imaginary), and it contains 3, 0 which makes 3, 0 a solution.

Answer 2

Answer: x=3

Step-by-step explanation:

The graph never crosses the y axis.

The point (3,0) is on the graph.

So are all points (3,y) with y any real number.

There can't be a slope because x never changes.
