You factor the numerator and denominator and cancel the common factors. So maybe that should help you
Answer:
The solution will be negative.
Step-by-step explanation:
I'm not quite sure what sort of answer you're looking for though.
Answer:
this answer should be -6x - 3
Step-by-step explanation:
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.
First we need to find our slope, to do this we take the change in y over the change in x like so:
(15-12)/(4-7) = - 3/4
The slope perpendicular to this is 4/3.
