Question

Y = 10x + 3
y = 5x + 2
Is it one solution, no solutions, or infinitely many solutions?

Answer 1

one solution: (x, y) = (-0.2, 1)

Explanation:

The y-coefficients are the same and the x-coefficients are different. That means the lines have different slopes, so they must intersect. The solution is at the one point of intersection.
