Question

What is the slope between the following points: (8, –1) and (–7, 4)?. . . A.1/3. B. 3. C. -1/3. D. -3

Answer 1

the answer is D. -3
you subtract x2 for x1 over y2 for y1 then you'll get 15/-3 then simplify the fraction

Answer 2

The slope of the line given 2 points is calculated by the equation,
m = (y2 - y1) / (x2 - x1)
where m is the slope, x's and y's are the abscissas and ordinates of the points. Substituting the known values,
m = (4 - -1) / (-7 -8) = -1/3
Therefore, the answer is letter C. -1/3.
