Question

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

Answer 1

Y=3x+2. I believe





.............yay.............

Answer 2

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, $m=\frac{y2-x2}{y1-x1}$ or $\frac{rise}{run}$ to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.

$m=\frac{5-2}{1-0} =\frac{3}{1} =3$            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
