Answer:
Sure, I'd be happy to help! The equation of the line that passes through the points (1,-3) and (4,-15) can be written in point-slope form as:
$$y - 1 = (-3) + 4(x - 1)$$
$$y - 1 = -4x + 11$$
Here, the point-slope form is used, where the slope is -4 and the y-intercept is 1.
The equation of the line is: y - 1 = -4x + 11.
