Question

Given the endpoints of line CD as C(-4, 7) and D(0, -3), what is the slope of line CD?

a) -2
b) 2
c) -1
d) 1

Answer 1

The slope of line CD is -2.5.

Step-by-step explanation:

To find the slope of a line given two points, you can use the formula: slope = (y2-y1)/(x2-x1).

In this case, the coordinates of point C are (-4, 7) and the coordinates of point D are (0, -3).

Substituting the values into the formula: slope = (-3 - 7) / (0 - (-4)) = -10 / 4 = -2.5.

Therefore, the slope of line CD is -2.5.
