Question

Give reasoning for the answer and I will give brainy to whoever is correct!

Answer 1

1. The graph is non-proportional because it starts from (0, 2).

2. The slope of the line is 3.

3. y=3x+2

Explanation:

The graph is non-proportional since it didn't start from the origin (0, 0). If the graph starts from the origin, then it's proportional.

To find the slope of the line, use this equation,
`m=(y2-x2)/(y1-x1)` or
`(rise)/(run)` to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.

`m=(5-2)/(1-0) =(3)/(1) =3` I chose (0, 2) and (1, 5) to find the slope

Once you find the slope, write the equation in y=mx+b form to find what b is with one of the points given.

`2=3(0)+b`

`-0`
`-0`

----------------------

2 = b

Equation of the line: y=3x+2
