I believe that 21 is d 27 over 17
I believe that 22 is d because 16 divided by 3.20 is 5
sorry if I am wrong
I hope this helps you
Answer:
Part 1) 
Part 2) The equation satisfy the set of coordinates (see the explanation)
Step-by-step explanation:
step 1
Find the linear equation
The rule for the linear equation states that y is three more than twice x.
so
The variable y is equal to the number 2 multiplied by x plus the number 3

step 2
Prove that the equation satisfies the set of coordinates
substitute the value of x and the value of y in the linear equation and then compare the results
a) (-1, 1)

----> is true
so
The equation satisfy the ordered pair
b) (0, 3)

----> is true
so
The equation satisfy the ordered pair
c) (-1/3,7/3)

----> is true
so
The equation satisfy the ordered pair
therefore
The equation satisfy the set of coordinates
Answer:
The answer to your question is the second option, both coordinates should be negative.
Step-by-step explanation:
The point Hassam plotted was (-0.5, -0.25). If he wanted to plot point (0.5, 0.25):
-First, he should have counted two squares to the right
- then one square up.
Because both coordinates are positive this point must be in the first quadrangle not in the third.
