Answer:

y = x - 2

Explanation:

The general structure of an equation in slope-intercept form is:

y = mx + b

In this formula, "m" represents the slope and "b" represents the y-intercept. Before writing our equation in this form, we first need to find the slope. The slope can be found using the point-slope formula:

y₁ - y₂ = m(x₁ - x₂)

In this formula, "m" represents the slope, "x₁" and "y₁" represent the values from Point One, and "x₂" and "y₂" represent the values from Point Two. You can find the slope by plugging the values from the points into the equation and then simplifying.

x₁ = 0 x₂ = -3

y₁ = -2 y₂ = -5

y₁ - y₂ = m(x₁ - x₂)

(-5 - (-2)) = m(-3 - 0)

-3 = m(-3)

1 = m

Now that we have a value for the slope, we can use the values from either one of the points to solve for the y-intercept (from the slope-intercept form equation).

m = 1

x = 0

y = -2

y = mx + b

-2 = (1)(0) + b

-2 = 0 + b

-2 = b

Therefore, the equation of the line in slope-intercept form is:

y = x - 2
