Answer:-6/8Step-by-step explanation:The slope formula is y2-y1 ____ x2-x1In the ordered pair (-20,4)-20 is x1 the first x and 4 is x1 -12 is the x2 i.e. 2nd point and -10 is y2 i.e. 2nd point on y axisso we plug in the value to the formula -10-(-4) two negatives become + _____ -12-(-20) so -10+4 -6 6 ____ = ___ = - _ -12+20 8 8(remember you subtract and the signs are different you subtract and use the sign of larger number)
