The rise is the vertical distance between the two points, which is the difference between their y-coordinates. That makes the rise y2 − y1. The run between these two points is the difference in the x-coordinates, or x2 − x1.
-2 - 3 -(-4)= -2 - 3 + 4
-2 - 3 + 4
-5 + 4
= -1
Answer:
D) 70 ft
Step-by-step explanation:
1 inch = 20 feet
3 1/2 inches= 20 feet*3 1/2 inches
= 70 ft
20 and 8 make a product of 160
and their difference is 12
When you divide something by 3/4, there's no way something can decrease, unless the number is a fraction below 3/4.
Since in Step 2, they divided 27 by 3/4, but ended up with 20 1/4, that means that they got step 2 wrong, because 27 / (3/4) is equal to 27 * 4/3 = 36
(This is because dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.)
So therefore they got Step 2 wrong.
