Answer:
The integer would -3.
Step-by-step explanation:
Think of it this way:
The elevator goes +7 (Positive = Up) and then -4 (Negative = Down). What is 7-4? That's easy it's just 3. But since the floor level goes down, <u>it would be negative.</u> So you just make it -3.
Check your work:
If we went up from the 4th floor by three, we would get up to the 7th floor.

784=20x+28y
30 = x + y
x=urban
y=highways
so isolate a variable then substitute
30 - x = y
substitute:
784 = 20x + 28(30-x)
784 = 20x + 840 - 28x
784-840 = 20x - 28x +840 -840
-56/8 = -8x/8
7 = x
substitute back in
30 = x + y
30 = 7 + y
30-7 = 7 - 7 + y
y = 23
Answer:
y = -2x - 4
Step-by-step explanation:
-2 is our slope
-4 is our y intercept (the point which the line crosses the y axis)
