Answer: The final option: x + 2y = -4
Explanation:
So, the graph's y-intercept is -2, so here's how the function would be set up as:
y = mx - 2
As for the slope, we could find two points, or we can notice a pattern on the graph itself. Let's do the latter.
So, it rises down one unit, and goes to the right two units. Remember, rise over run is the slope, so -1/2.
y = -1/2x - 2
Because the set of answers do not have any fractions, let's multiply both sides by two.
2y = -x - 4
Also, let's get "x" and "y" on the same side.
2y + x = -4
The one matching this answer is the final option.
