Step-by-step explanation:
The first one is A and then the next one I believe should be 210 for both
The correct question is
<span>Jack and Jill are trying to find the slope of a line segment connecting two points, (x1, y1) and (x2, y2). Jack uses the formula m = (y2 - y1)/( x2 - x1) . Jill mistakenly uses a different formula, but still gets the right answer. Which formula COULD she have used? A) (x2 - x1)/( y2 - y1) B) (y1 - y2)/( x1 - x2) C) (x1 - x2)/( y2 - y1) D) (y2 - y1)/( x1 - x2)
we know that
the correct formula to calculate the slope is
m=(y2-y1)/(x2-x1)
then
</span><span>if both numerator and denominator multiply it by -1
</span>
m=-(y2-y1)/-(x2-x1)---------> m=[-y2+y1]/[-x2+x1]
m=[y1-y2]/[x1-x2]
therefore
the answer is the option
B) (y1 - y2)/( x1 - x2)
