Question

A line passes through the point (7, 3. and has a slope of 2. Write an equation for this line.

Answer 1

y = 2x - 11.

Explanation:

Use the point-slope form of the straight line.

y - y1 = m(x - x1) where m = slope and (x1, y1) is the given point.

Here m = 2 and (x1, y1) = (7,3) so the equation is:

y - 3 = 2(x - 7)

y - 3 = 2x - 14

y = 2x - 11
