Question

What is the slope between point A (-9, 4) and B ( 3, -2)

a)1/2
b)-1/2
c)2
d)-2
e)3/2

Answer 1

Slope can be calculated using the formula: m=
`(y2 -y1)/(x2-x1)`

y1/x1 represents the first number in the bracket

y2/x2 represents the second number in the bracket

Calculation

m =
`(y2 -y1)/(x2-x1)`

m =
`(4 - (-2))/((-9)-3)`

m= 6/-12

m= -0.5 or -1/2

Therefore, the answer is B.
