Question 8 • GA-Algebra: Concepts and Connections A

A line passes through the point (0, –1) and has a positive slope. Which of these points could that line pass through? Check all that apply.

Answer
A
(12, 3)
B
(–2, –5)
C
(–3, 1)
D
(1, 15)
E
(5, –2)

Explanation

For each point, calculate the slope from (0, −1) using (y₂ − y₁)/(x₂ − x₁). For A, B, and D, the slopes are 4/12, (−4)/(−2), and 16/1, all positive. The slopes to C and E are negative, so those points cannot lie on the line.
