Final answer:
The equation of the line passing through the given points (-14, -6) and (6, -6) in slope-intercept form is y = -6.
Step-by-step explanation:
To write the equation of a line in slope-intercept form, we need to find the slope and the y-intercept. The formula for the slope is: m = (y2 - y1) / (x2 - x1). Using the given points (-14, -6) and (6, -6), the slope is 0. Now that we have the slope, we can plug it into the slope-intercept form equation y = mx + b. Since the y-coordinate is -6 for both points, the y-intercept is also -6. Therefore, the equation of the line in slope-intercept form is y = 0x - 6, which simplifies to y = -6.
