I would have used graph b. Because it shows the decrease more than graph a.
Answer: 115 - (-30) = 115 + 30 = 145 degrees change
Step-by-step explanation:
I think it’s 15..
cause you replace the x with -5 and solve the problem
If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.
