Answer:

Explanation:

The equation of the line can be found using the two-point form:

y = mx + b

where m is the slope between the two points and b is the y-intercept.

For the given points A and B:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) is point A and (x2, y2) is point B

m = (-1 - 7) / (-3 - 1) = -8/ -4 = 2

Next, find b using one of the points and the slope:

b = y - mx

b = 7 - 2 * 1 = 5

So, the equation of the line is:

y = 2x + 5
