Question 10 • LJISD-TX-Precalculus-B-CR

Find the equation of the line specified.The line passes through the points ( 2, 1) and ( 5, 4)

Answer
A
y = x + 1
B
y = -x - 1
C
y = x - 1
D
y = x + 3

Explanation

The slope through (2, 1) and (5, 4) is (4 − 1)/(5 − 2) = 1. Using y = mx + b and the point (2, 1), we get 1 = 2 + b, so b = −1. The equation is y = x − 1, choice C.
