What is the equation of the line through (1, 2) and (3, 8)?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. y = 3x - 1.

Slope(m) = (y2−y1)(x2−x1)(y_2 - y_1)\over(x_2-x_1)

Slope = 8−23−18 − 2\over3 − 1 = 626\over2 = 3

Using point-slope form:

y − 2 = 3(x − 1)

⇒ y − 2 = 3x − 3

⇒ y = 3x − 1
