Point Slope Formonly needs slope and a pointto write the equation of the line
Slope: m Point: (x1 , y1)
y y1 = m(x x1)Example
Write the EQ of a line with slope = 4 that goes through (1.5 , 3)
Write the EQ of a line with slope = .5 that goes through (2 , 0)
Write the EQ of a line that goes through (1 , 3) and (0 , 4)
