Question

Which of the following is the slope between the two points (2, 3) and (1, 4)? (a.) -1 (b.) 1 (c.) -1/3 (d.) 1/3

Answer 1

To find the slope between two point, use the formula:
Slope = Rise/Run = (y2-y1)/(x2-x1)

Answer 2

y2=4 , y1=3 , x2=1 , x1=2
Plug in and solve

Answer 3

so we have 2=x1 3=y1 1=x2 4=y2 no?

Answer 4

ok so then (4-1=3)/ (1-2=-1) and the calculator says that it is -3. Am I correct?

Answer 5

oh -1/3 ok ok ok :D
