1. To plot the segments AB and CM on the coordinate plane, we can use the given coordinates of the points A, B, C, and M.

The segment AB can be plotted by connecting the points A(1, 3) and B(4, 1). The segment CM can be plotted by connecting the points C(-3, 1) and M(2, 1).

To find the coordinates of the intersection points, we need to find the equations of the two lines AB and CM, and then solve for their intersection points.

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

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

where (x1, y1) = (1, 3) and (x2, y2) = (4, 1). Substituting these values, we get:

y - 3 = -2/3 * (x - 1)

Simplifying, we get:

y = -2/3 * x + 7/3

Similarly, the equation of the line CM can be found using the point-slope form:

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

where (x1, y1) = (-3, 1) and (x2, y2) = (2, 1). Substituting these values, we get:

y - 1 = 0 * (x + 3)

Simplifying, we get:

y = 1

Now, to find the intersection point of the lines AB and CM, we can solve the system of equations:

y = -2/3 * x + 7/3 y = 1

Substituting y = 1, we get:

1 = -2/3 * x + 7/3

Solving for x, we get:

x = 5

Substituting x = 5, we get:

y = 1

Therefore, the intersection point of the lines AB and CM is (5, 1).

Similarly, we can find the intersection point of the lines AC and BM. The equation of the line AC can be found using the point-slope form:

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

where (x1, y1) = (1, 3) and (x2, y2) = (-3, 1). Substituting these values, we get:

y - 3 = -1/2 * (x - 1)

Simplifying, we get:

y = -1/2 * x + 7/2

Similarly, the equation of the line BM can be found using the point-slope form:

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

where (x1, y1) = (2, 1) and (x2, y2) = (4, 1). Substituting these values, we get:

y - 1 = 0 * (x - 2)

Simplifying, we get:

y = 1

Now, to find the intersection point of the lines AC and BM, we can solve the system of equations:

y = -1
