You never put in what the question was.
Answer:
Below.
Step-by-step explanation:
3x + 5y = 15
Subtract 3x from both sides:
5y = -3x + 15
Divide through by 5:
y = -3/5 x + 3 <-----------slope-intercept form
Answer:
y = -2x - 3
Step-by-step explanation:
y = mx + b
-15 = -2(6) + b
-15 = -12 + b
b = -3
y = -2x - 3
Proportional numbers are numbers with the same equivalent ratio
98/126 is proportional to 84/108
The number is given as:

Reduce fraction to the lowest term

Reduce 86/110 to the lowest term

Divide by 2/2

43/55 is not equivalent to 7/9
Reduce 98/126 to the lowest term

Divide by 14/14

7/9 is equivalent to 7/9.
Hence, 98/126 is proportional to 84/108
