Here is a picture of the graph put into desmos
Desmos is super easy all you have to do is put in the equation and it graphs it for you but you can also use it as a regular calculator.
Answer:

Step-by-step explanation:
First you can find the slope of the line that would pass through those two points using the formula:
m = 
m = 
m=5/4
Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.
So,

(don't leave out the parentheses!)
Answer:
1/16
Step-by-step explanation:
We know that a^ -b is equal to 1 / a^b
That means
4^-2 = 1/ 4^2 = 1/16
D since you said it equals seven then the possible answer is out of C or D but there wasn't a negative sign so I went with the positive answer.
Answer:
x = 120
Step-by-step explanation:
Since they are supplementary, they add up to 180 degrees.
So, you can say x + x/2 = 180
Then, you would solve it like an algebra problem.
Multiply both sides by 2
2x + x = 360
Simplify
3x = 360
Divide both sides by 3
x = 120
