The slope (m) can be calculated using the formula:

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

Let's use (-1, 3) as our first point (x1, y1) and (-3, 1) as our second point (x2, y2):

m = (1 - 3) / (-3 - (-1))

m = -2 / (-3 + 1)

m = -2 / (-2)

m = 1

Now that we have the slope (m = 1), we can use either of the given points and the slope to find the y-intercept (b) using the slope-intercept form of a linear equation, which is y = mx + b.

Let's use the point (-1, 3):

3 = 1 * (-1) + b

3 = -1 + b

b = 3 + 1

b = 4

Now we have the slope (m = 1) and the y-intercept (b = 4), so we can write the equation in slope-intercept form:

y = mx + b

y = 1x + 4

y = x + 4

Therefore, the equation in slope-intercept form for the points (-1, 3) and (-3, 1) is y = x + 4.
