Answer:

y = 2/3x + 3

Explanation:

Use rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(3 - 1) / (0 + 3)

= 2/3

So, the slope is 2/3

Plug this and another point into y = mx + b to find b:

y = mx + b

3 = 2/3(0) + b

3 = b

Then, plug b and the slope into y = mx + b

y = 2/3x + 3 is the equation of the line
