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

Answer:
1. The graph is non-proportional because it starts from (0, 2).
2. The slope of the line is 3.
3. y=3x+2
Step-by-step 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, [tex]m=\frac{y2-x2}{y1-x1}[/tex] or [tex]\frac{rise}{run}[/tex] to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.
[tex]m=\frac{5-2}{1-0} =\frac{3}{1} =3[/tex] 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.
[tex]2=3(0)+b[/tex]
[tex]-0[/tex] [tex]-0[/tex]
----------------------
2 = b
Equation of the line: y=3x+2
