Answer:
(0,5), (2,4), (4,3), (6,2), (8,1), (10,0), (12,-1), (14,-2), (16,-3), (18,-4), and (20,-5)
Step-by-step explanation:
The given linear equation is :
Or
Any ordered pair that satisfies this equation is a solution.
When x=0,
(0,5) is a solution
When x=2,
(2,4) is a solution.
When x=4,
(4,3) is a solution;
When x=6:
(6,2).
When x=8,
Another solution is (8,1)
When x=10,
(5,0) is a solution
When x=12,
(12,-1) is a solution.
When x=14,
When x=16, we get:
When x=18, we get:
R=-7, you have to put each answer in the equation, therefore; 21=42-3(-7) So you have to do multiplication (PEMDAS, if you arent aware of that acronym then it stands for the order of what to do with an equation, Parentheses get solved first, then Exponents, then multiplication, then division, then addition, then finally subtraction. Solving in that order will solve your answer correctly.) With -3 times -7 which gives you 21. Then you do 42 - 21 which equals 21. So 21 = 21.
The correct answer is: "(-1, -2)" .

Note: By examining the point of intersection of the lines of the 2 graphs show in the "image attached", we can see that the point of intersection is at: "(-1, 2"); that is: "x = -1, y = 2" .
