Y 1 y 1 y 1 the. The point-slope formula uses the slope and the coordinates of a point along the line to find the y-intercept. M y 2 y 1 x 2 x 1 It is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope.
The basic formula for a linear equation is y mx b where m is the slope.
Y-intercept of the line Now looking at the question4y -3x 3 0 It is quite clear that this equation needs to be changed into the slope-intercept form for us to find the slope. The point-slope formula uses the slope and the coordinates of a point along the line to find the y-intercept. Easy as PiFor fun brainteasers and IQ puzzles to build up your math brain.
