The answer the third option (4,2)
Answer:
1. not proportional because it's increasing in different values
2. proportional because the value is increasing equally
3. proportional because the values are increasing in equal amount
4. Proportional because it's increasing in equal amounts
(6xy - 8x^2)/2x
=
2x(3y - 4x)
1. Pick two points on the line and determine their coordinates.
2. Determine the difference in y-coordinates of these two points (rise).
3. Determine the difference in x-coordinates for these two points (run).
4. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
