Hi
-6 /7 = -x / 84
Cross multiply
-7x = -6 * 84
-7x = -504
x = -504/-7
x = 72
M = 44
b = 48
Equation: y = 44x + 48
Proportional
Positive slope
Answer:
Don’t really have a step by step explanation, I guessed and got (4,32)
The first thing we are going to do to graph our equation is solve them for

:
For our first equation:



For our second equation:


Now, we just need to use the graphing utility to graph our equations:


We can conclude that the graph of the equations is:
-9 duh
It says the first week look at the numbers and then the top row with numbers. the only one that matches up is -9
