Final answer:
The equation of the line with a slope of 3 that passes through the point (-2, -10) is y = 3x + 4.
Step-by-step explanation:
The equation of a line can be written in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept. Since the slope is given as 3, we substitute 3 for m in the equation. To find the y-intercept, we substitute the coordinates of the given point (-2, -10) into the equation and solve for b. Plugging the values for m and b into the equation, we have y = 3x + 4.
