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)
Add them all together and divide by the number of variables here there are four and the answer is 1.25 or 5/4

Step-by-step explanation:
Answer:
The area of frame is 180 square meters.
Step-by-step explanation:
We are given the following in the question:
Dimension of rectangular painting:
Length, l = 20 cm
Width, w = 16 cm
Dimension of frame:
Length, L = 25 cm
Width, W = 20 cm
We have to find the area of frame.
Area of rectangle =
Area of frame =
Thus, the area of frame is 180 square meters.
