what is the formula for point-slope? The question is (0,4) and (-5,5) it says to write an equation in point slope form?
( 0 , 4) and (-5, 5 )
Find the slope :
Subtract the y coordinates in some order 5 - 4 1
____________________________________ = ____ = ____
Subtract the x coordinates in the same order -5 - 0 - 5
So using either points - I ' ll choose (0, 4) we have the point slope form
y - y coordinate of our point = ( slope ) ( x - x coordinate of our point )
y - 4 = (-1/5) ( x - 0 )
And that's point-slope form
