Question

Determine the slope from the data in the table below.
x -2 , -1, 0, 1

y 2, 1.5, 1, 0.5
Select one:
a. 1/2
b. -1/2
c. 2
d. -2

Answer 1

(-2,2) x1 = -2 and y1 = 2
(-1,1.5) x2 = -1 and y2 = 1.5

slope formula : (y2 - y1) / (x2 - x1)
sub your points in and what do you get ?

Answer 2

Answer 3

its B right?

Answer 4

slope = (y2 - y1) / (x2 - x1)
slope = (1.5 - 2) / (-1 - (-2)
slope = -.5 / (-1 + 2)
slope = -0.5/1 or just -0.5 which is the same as -1/2.....it is B

Answer 5

cool thanks.

Answer 6

no problem :)
