Can you help with did pretty please I'm stuck help just a, c ,d thanks luv.

a) The slope of the function is 3.

c) The equation is represented by .

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

(1)

Where:

- Slope, measured in number of pieces per minute.

- Time, measured in minutes.

- Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

- Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that and , then the following system of linear equations is formed:

(2)

(3)

The solution of the system of equations is:

and

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

(4)

d) The y-intercept of the function is 35.

e) none of the above because the measure of angle cba is 101°
