Answer:

y = 3x - 1

Explanation:

In order to write this equation in slope intercept form, we first need to find the slope. I will take two points (2,5) and (1,2). We can find the slope either by counting the slope with
(rise)/(run) or we can calculate it using the formula
(y2-y1)/(x2-x1)

For the sake of simplicity, we will count it using
(rise)/(run). Counting the slope between the two points, we get
(3)/(1) which simplifies to 3.

The y intercept crosses between the point (0, -1), so our y intercept is -1.

Thus, our equation of the line will be
y=3x-1
