Question

1. if a system of linear equations has one solution, what does this mean about the two lines?

□ a) parallel lines □ b) the same line □ c) intersecting lines

1. an inequality using a > or a < has a ________ line

□ a) invisible □ b) solid □ c) dashed

Explanation:

For question 3, parallel lines have no solution as they never meet, and the same - line has infinitely many solutions. Intersecting lines meet at a single point, which is the one - solution of the system of linear equations.
For question 4, inequalities with > or < do not include the points on the line itself, so a dashed line is used to represent the boundary.

Answer:

1. c) Intersecting lines
2. c) dashed
