Question

Which of the following is the equation of a line that passes through the points (0,6) and (2,10)?

Answer 1

y = 2x + 6

Explanation:

first find the gradient using y2 - y1 / x2 - x2

=10 - 6 / 2 - 0

gradient m = 2

use any of the 2 points to sub into the equation

then use the equation y - y1 = m (x - x1)

y - 10 = 2 (x - 2)

y - 10 = 2x - 4

y = 2x + 6
