How to find the y intercept when given 2 points

The defintion of slope is $$ \text{slope} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}$$ where $(x_1,y_1)$ and $(x_2,y_2)$ are any two points on the line. So, if you let $(x_1,y_1) = (0,-3)$, and using the fact that the slope is 3, then any other point on the graph can be obtained by $$ 3 = \frac{y - (- 3)}{x - 0}$$ so $$ y = 3x - 3$$
