Answer:


Explanation:

I'm imagining you are trying to find the equation of a line. Keep in mind that the equation of a line is in the form of y = mx + b.

y = mx + b

The slope is one. That means we already have one part of our equation set. Keep in mind...

m = slope

so

y = 1x + b

We want to find b in our equation. We will now plug in our variables. What I mean is that we will replace y with -4 and x with -2. Then we will simply the equation until we find out b, the y-intercept. (The y-intercept is the point where the line intersects the y-axis.)

-4 = 1 (-2) + b

-4 = -2 + b

b = -2

Since we know the slope and the y-intercept, we can make the equation of the line.

y = mx + b

m = slope

b = y-intercept

Let's plug in the information which we have found.

y = 1x - 2

The equation of the line is

y = x - 2
