How could you use repeated addition to show ratios equivalent to 1:3 on a graph?

3:1

Step-by-step explanation:

Step-by-step explanation:

Use a table with x and y, every time x increases, it increases by 3, and every time y increases, it increases by 1

Repeated addition:

x                    y

0 + 3             0 + 1

3 + 3              1 +1

6 + 3              2 + 1

9 + 3               3 + 1

12 + 3             4 + 1

15 +3              5 + 1

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

answer: the answer is   graph (a)
