A line passes through the points (x,2) and (3,-4) and has a slope of 2. What is the value of x?
Show answer & explanation
Correct answer: C
Explanation
Given:
The line passes through the points (x, 2) and (3, −4) and has slope = 2.
Formula:
m = (y₂ − y₁) / (x₂ − x₁)
2 = (−4 − 2) / (3 − x)
2 = −6 / (3 − x)
2(3 − x) = −6
6 − 2x = −6
−2x = −12
x = 6
