Re: what is point slope form?  TOPIC_SOLVED

y = mx + b is slope-intercept form, not point-slope form. The point-slope formula is y - y 1 = m(x - x 1 ), where you will most likely be given a point (x 1 , y 1 ) and a slope (m) that you can then substitute into the formula by replacing those variables with the numbers you were given in the probl...
