Final answer:
The equation representing the line passing through the point (7, -2) with a slope of -3 is y = -3x - 2.
Step-by-step explanation:
The equation that represents the line passing through the point (7, -2) with a slope of -3 is:
y = mx + b
where m is the slope and b is the y-intercept. Plugging in the values, we get:
y = -3x + (y-coordinate of the point) = -3x + (-2) = -3x - 2
Therefore, the equation representing the line is y = -3x - 2.
