Question

Complete the table with values for x or y that make this equation true : 3x+y=15.

Answer 1

Answer is in the attachment. A graph and a filled in table.

Step by step

I graphed the line and found the matching x and y points. Example, given x=2 on the table, find x =2 and find where y crosses, that’s your y value of 9. Next is a y=3, find that point on the graph, where does the line cross for x? At x=4. Continue with the remainder numbers on the table. Graph all the points.


Table as follows

2 4 6 0 3 5 2.3333
_________________________
9 3 -3 15 6 0 8

Answer 2

Explanation:

So first, with the given table you need to "plug-in" the numbers that are there for x and y.

Ok, for example 2 is listed in the "x" row. So plug it 2 for "x":

3x+y=15

3(2)+y=15

6+y=15

-6 -6

y=9

So do this for all of them...the same goes with all of the values...just plug in one, complete the steps then you'll get the answer for the other variable.

Hope this helps!
