Which linear function shows a direct variation?

Graph A

On a coordinate plane, a line goes through points (negative 1, 0) and (0, 2).
Graph B

On a coordinate plane, a line goes through points (0, negative 2) and (0, 1).

Graph C

On a coordinate plane, a line goes through points (0, 2) and (1, 0).

Graph D

On a coordinate plane, a line goes through points (0, 0) and (1, negative 2).
Graph A
Graph B
Graph C
Graph D

Graph D.

Step-by-step explanation:

The line goes through the origin, and therefore shows direct variation.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
