Answer:
Step-by-step explanation:
Honestly not sure what all the numbers you put down were (numbers for the graph?), but here is how to find the slope :)
First, find two "exact" points!
I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is
(I hope this helps, have a nice day!)
Answer:
Any number other than 2
Step-by-step explanation:
Well if we plug in any number other than 2 like 1 for the blank and distribute,
the right side becomes,
3x + 6 = 3x + a number other than 6
Parallel lines have the same slope but different y intercept.
Look at the image below ↓
<em>Thus,</em>
<em>to make the equation have no solution the blank has to be any number other than 2.</em>

First get rid of the decimal points on both numbers so it becomes 72/8
then enter that into your calculator the answer is 9
hope that helps
Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way
long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2
smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2
