Answer:

y = -3x - 1

Explanation:

The equation for a line in slope-intercept form is:

y = mx + b,

where m is the slope of the line, and b is the y-coordinate of its y-intercept.

We can first solve for the slope of the line using the formula:

m = rise / run,

inputting the given coordinates to solve for rise (Δy) and run (Δx).

m = (-4 - 2) / (1 - (-1))

m = -6 / 2

m = -3

So, the slope (m) of the line is -3.

Next, we can find the y-coordinate of the line's y-intercept by looking at where the line crosses the y-axis. We can see that this happens when y is -1. Therefore, b = -1.

Finally, we can construct an equation using the information we just solved for.

y = -3x - 1
