Question

Line AB contains points A (0, 1) and B (1, 5). The slope of line AB is
−4
negative 1 over 4
1 over 4
4

Answer 1

for any points (x1, y1) and (x2,y2)
the slope of the line joining them is
(y2-y1) / (x2 - x1)

Answer 2

which do you think it is ?

Answer 3

A

Answer 4

no.. not -4

Answer 5

let y2 = 5 , y1 = 1, x2 = 1 and x1 = 0 in the above formula and you'll have it

Answer 6

slope = (5-1)/ (1-0) = ?

Answer 7

the slope is 4 because you would rise 4 and run 1 if you understand that

Answer 8

yes rise = 5-1 , run = 1-0
