Answer:
1.5
Step-by-step explanation:
The rate of change is also the slope or m. This equation is in slope intercept form which is y=mx+b. m is the rate of change. m=1.5.
Answer:
D) -40
Step-by-step explanation:
Any temperature described as below zero is negative. 40 below zero is -40.
Two points: (-5,7), (0,2)
Find slope: (2-7)/(0+5) = -5/5 = -1
Y intercept is given: 2
Y = -1x + 2
First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
Answer: You simplify it.
Step-by-step explanation: You have to take the numerator and the denominator, find the greatest common factor, and divide it until it is at its simplest form.
