Question

What is the slope of the line containing the points W(4,8) and X(-6,18)?

A) -5

B) 1

C) 5

D) -1

Answer 1

The slope of the line through points W(4,8) and X(-6,18) is calculated to be -1, indicating a line with a negative slope.

Step-by-step explanation:

The slope of the line containing points W(4,8) and X(-6,18) can be calculated using the slope formula, which is the change in y divided by the change in x (rise over run). This is given by (y2 - y1) / (x2 - x1). Applying this formula to the given points:

Slope (m) = (18 - 8) / (-6 - 4) = 10 / -10 = -1.

So the slope of the line is -1, which means the line has a negative slope. Therefore, the correct answer is D) -1.
