Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
Try to use the total which is 650 - 247
by that will give you the answer
Here is your function:
You're looking for f(-1). To get your answer, you have to replace all the x's with -1.
Here is your new equation:
Multiply 2 by -1
<em>Remember:</em>
MULTIPLYING
- Positive(+) times negative(-) is equal to negative
- Positive(+) times positive(+) is equal to positive
- Negative(-) times negative(-) is equal to positive
- Negative(-) times positive(+) is equal to negative
DIVIDING
- Positive(+) divided by positive(+) is equal to positive
- Positive(+) divided by negative(-) is equal to negative
- Negative(-) divided by positive(+) is equal to negative
- Negative(-) divided by negative(-0 is equal to positive
Since you're multiplying a negative number by a positive number, the answer will be negative.
Here is your new equation:
Add -2 and 2:
That means your answer is 0
