Reggie has 6 red pencils, 4 green pencils, and 5 blue pencils. If he picks out one pencil without looking, what's the probability that the pencil he picks will be green

4 green/ 15 total

Step-by-step explanation:

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
