Question

1. in the context of linear functions, what does it mean if two lines have the same slope?

a. they are parallel
b. they intersect at the y-axis
c. they are perpendiculard. they have the same y-intercept

Explanation:

In linear functions, the slope determines the steepness and direction of a line. Lines with identical slopes maintain the same steepness and never intersect, which is the definition of parallel lines. Options b and d relate to y-intercepts, not slope, and perpendicular lines have slopes that are negative reciprocals, not equal.

Answer:

a. They are parallel
