I believe its either A or C
477>80 is correct
-4.5<3 this one is also correct
Answer:
16) 
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using 
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
Answer:
y = x + 1.8
Step-by-step explanation:
X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x
