Vanyuwa [196]
To solve this questions, we can turn 2 into a fractions.

2 as a fraction is 2/1 (because 2 divide by 1 is still 2)
We can now use this to get our answer. 

1/3  ÷ 2/1 
=  1/3 × 1/2    (flip the fraction and then multiply)
= 1/6          (1 x 1 / 3 x 6)

Or 0.16666.. as a decimal

y = 3x + 3

Step-by-step explanation:

First, you check for the y-intercept, which is 3 for this equation.

In order to find the slope, pick two points and apply the slope formula.

I would just use rise/run. The slope should be 3/1.
