The equation $y = -x - 4$ is in the slope-intercept form $y = mx + b$, where:

• $m$ is the slope.
• $b$ is the y-intercept.

From the given equation:

• $m = -1$ (this is the slope).
• $b = -4$ (the y-intercept).

Slope: $-1$

1. How do you calculate the slope between two points on a line?
2. What does a negative slope represent graphically?
3. How would the line change if the slope were $1$ instead of $-1$?
4. How do you rewrite the equation $y = -x - 4$ in standard form?
5. How do you find the x-intercept for this equation?

Tip: The slope determines how steep a line is and the direction it leans. A negative slope means the line descends from left to right.
