1. Refer to the equation 3x − 5y = 15. (a) Create a table of values for at least 4 points. Show your work on how you found the values for each coordinate pair, and validated the points were on the line.

Work for Point 1
Work for Point 2
Work for Point 3
Work for Point 4

Answer: For this problem, you cannot go over 10! so remember guys you can graph it however you want for example if you wanted to you could do -3/5(-2) + 3 for the first point but you would have to solve it. the next one would be maybe -3/5(-1) + 3 if you wanted to go up by plus one REMEMBER this is your OWN graph so do whichever number order you want it doesn't matter you can increase by 1 or 2 or 3 but the final point shouldn't be over ten or you will get the problem wrong. Good Luck I hope I get an A and I hope you guys get A's as well. Do ur absolute best on this

Answer:

(0, 3 ), (5, 0), (10, -3), (15, -6)

Explanation:

3x − 5y = 15

-5y = 3x + 15

y =
-(3)/(5) x + 3

Point 1: (0, 3 )

y = -3/5(0) + 3

y = 0 + 3

y = 3

Validate:

3 = -3/5(0) + 3

3 = 3

Point 2: (5, 0)

y = -3/5(5) + 3

y = -3 + 3

y = 0

Validate:

0 = -3/5(5) + 3

0 = 0

Point 3: (10, -3)

y = -3/5(10) + 3

y = -6 + 3

y = -3

Validate:

-3 = -3/5(10) + 3

-3 = -3

Point 4: (15, -6)

y = -3/5(15) + 3

y = -9 + 3

y = -6

Validate:

-6 = -3/5(15) + 3

-6 = -6
