A high school math teacher is grading her students' tests. The teacher spends about 4 minutes grading each test. The teacher has a total of 176 students. How long will it take the teacher to grade the tests? A.8 hours and 34 minutes
B.6 hours and 44 minutes
C.10 hours and 55 minutes
D.11 hours and 44 minutes

D

Step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
