The slope of XY can be found by using the formula:
slope = (change in y) / (change in x)
Using the coordinates of X(-2,4) and Y(-1,-3), we get:
slope of XY = (-3 - 4) / (-1 - (-2)) = -7 / 1 = -7
The slope of 7Z is undefined because it is a vertical line.
The slope of XZ can be found by using the formula:
slope = (change in y) / (change in x)
Using the coordinates of X(-2,4) and Z(2,5), we get:
slope of XZ = (5 - 4) / (2 - (-2)) = 1/2
