<u>Answer</u>
-4x - 2
<u>Explanation</u>
To get the function needed, first calculate the slope of the graph.
slope = (change in y) / (change in x)
= (2 - -2)/(-1 - 0)
= 4/-1
= -4
Now use one of the point (-1, 2) in the graph and a general point (x,y) to find the function.
-4 = (y - 2)/(x - -1)
-4(x + 1) = y - 2
-4x - 4 = y - 2
y = -4x - 4 + 2
= -4x - 2
∴ f(x) = -4x - 2
Answer:
Step-by-step explanation:
Divide 2 from both sides.
4x-2 = 4
Add 2 to both sides.
4x = 6
x = 1.5

Step-by-step explanation:
Order of operations PEMDAS
Do the multiplication and division first - each separately
Then add and subtract the answer you get to get the final answer.
Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation
If I'm right, then the process is
Y=2(3)+1 (putting 3 in place of x)
Y=6+1
Y=7
Which makes 7 your answer
