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, or
to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.
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 = b
Equation of the line: y=3x+2
