Given :

We are given the slope m = -2 and a point on the line (-2, -3).

To find :

The equation for the line in slope-intercept form

Solution :

We can use the point-slope form of the equation of a line to find the slope-intercept equation of the line:

y - y₁ = m(x - x₁)

Where (x₁, y₁) is the given point on the line.

Substituting the given values, we get:

y - (-3) = -2(x - (-2))

Simplifying:

y + 3 = -2(x + 2)

Expanding:

y + 3 = -2x - 4

Subtracting three from both sides:

y = -2x - 7

Therefore, the equation of the line that passes through the point (-2, -3) and has a slope of -2 is :

y = -2x - 7.
