Question

The the slope of a line is 2. Use the coordinates (3,10) of the labeled point to find the point slope equation of the line.

How?

Answer 1

Point-Slope Equation:

y - yo = m (x - xo)

M = Slope = 2
Xo and Yo = Coordinates;
Xo = 3
Yo = 10

-> y - 10 = 2 (x - 3)
-> y - 10 = 2x - 6
-> y = 2x - 6 + 10
-> y = 2x + 4

Answer: y = 2x + 4 is the point-slope equation of the line.
