Question

Which of the following is the equation of a line with the points (8, 3)(9, 5) and a slope of 2?

Answer 1

y = 2x - 19

Explanation:

Given the following data;

Points (x, y) = (8, 3) and (9, 5)

Slope = 2

To find the equation of line;

y - y1 = m(x - x1)

Where;

(x1, x2) = (8, 9)

(y1, y2) = (3, 5)

Substituting the value into the equation above;

y - 3 = 2(x - 8)

y - 3 = 2x - 16

y = 2x - 16 + 3

y = 2x - 19
