What is the slope of a line with an x-intercept of 5 and a y-intercept of 14?

-3
-2.8
5
2.8

The correct answer is: -2.8

The slope of a line can be calculated using the formula (y2 - y1) / (x2 - x1). In this case, the x-intercept is 5 and the y-intercept is 14, therefore we can assign these values as (x1,y1) and (x2,y2) respectively. Plugging these values into the formula, we get (14 - 0) / (0 - 5) = - 2.8. This is the slope of the line and option B is the correct answer. Option A (-3) is incorrect because the slope can never be negative in a line with a positive y-intercept. Option C (5) is incorrect because it is the value of the x-intercept, not the slope. Option D (2.8) is incorrect because it is not the correct calculation for the slope and
