Question

What is the slope of the line through points (4,8) and (7,-10]

A. -6
B. -1/6
C. 1/6
D. 6

Answer 1

Slope = (y2 - y1)/(x2 - x1)

= (8 + 10)/(4 - 7)

= 18/ (-3)

= - 6

Answer

A. -6

Answer 2

B.) -1/6 because solving for the slope you get the equation (7-4)/(-10-8) which simplifies to 3/-16 and then to -1/6.
