Question

What is the equation in point slope form of the line that passes through the point (2 , 4) and has a slope of 3

Answer 1

use point slope form y - y1 = M(x - x1)

y - 4 = 3(x - 2)  Plug into Point Slope form

y - 4 = 3x - 6    Distribute the 3

   -4         -4       Subtract 4 from both sides

y = 3x - 10    This is the equation of a line that passes through the point (2 , 4) and has a slope of 3
