Which situation cannot be represented by a linear function? a) a worker's monthly earning include a bonus of $25 and pay at a rate of $6 per hour he worked that month b) a student collects 15 pounds of cans every two weeks for a fundraiser. c) a writer uses twice as many pencils each week as he did the week before. d) a teacher writes down a check mark for every 15 minutes her students read silently.

c) A writer uses twice as many pencils each week as he did the week before.

Step-by-step explanation:

A) A worker's monthly earning include a bonus of $25 and pay at a rate of $6 per hour he worked that month

slope = 6 and y intercept = 25    

y = 6x+25

b) A student collects 15 pounds of cans every two weeks for a fundraiser.

15 cans every two weeks.  This is a line at 15

c) A writer uses twice as many pencils each week as he did the week before.

Week 1 =2

Week2 =4

Week3 = 8

This is exponential growth

d) A teacher writes down a check mark for every 15 minutes her students read silently.

This is a line at 1 checkmark

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
