Question

Both sides of an equation have linear expressions. The graph of one line has a positive slope. The graph of the other line has a negative slope. What are the possible number of intersections for this system?

0

1

2

infinite

Answer 1

B

Explanation:

Answer 2

Just 1

Explaination:

If one line has a positive slope and the other a negative slope, they are bound to intercept eventually, so that's why there can't be zero solutions. Two lines can't intercept each other twice, and if they have opposite slopes they can't have infinite solutions.
