Slope formula : (y2 - y1) / (x2 - x1)
(-2,-3)...x1 = -2 and y1 = -3
(1,1)...x2 = 1 and y2 = 1
time to sub and solve
slope = (1 - (-2) / (1 - (-3) = (1 + 2) / (1 + 3) = 3/4 <==
Number three is 80
Number three is 150
False Sometimes its different for all
Answer:
find the constant rate of proportionality
Step-by-step explanation:
Answer:
Only the floor area
has been covered
Step-by-step explanation:
Assuming that the floor of the room is rectangular, then its area is equal to the product of its length times its width.

Let's now call A 'the area that was covered with tiles.
We know that half the length was covered, then:


So:


Finally:
