point-slope formula
[point-slope formula|point-slope formula] is a formula used to find the equation of a line when the slope and a point on the line are known.
Definition
point-slope formula is a formula used to find the equation of a line when the slope and a point on the line are known. Zero in the denominator means the slope is undefined, making it impossible to apply the point-slope formula.
Mechanism
point-slope formula The point-slope formula incorporates the slope and a point to calculate the equation of a line. Using the formula, substitute −3 for m and the point ( 4 , 8 ) for ( x 1 , y 1 ).
Causes
point-slope formula Zero in the denominator means the slope is undefined, making it impossible to apply the point-slope formula. Next, the point-slope formula is used with a slope of 7 3 and either point.
