What is the slope of the line represented by the equation below?y=-2/3x+3 A-2/3 B. 2/3 C.2 D.x
Black_prince [1.1K]

ANSWER

A.

-  \frac{2}{3}

EXPLANATION

The given equation is

y =  -  \frac{2}{3}x + 3

This equation is already in the form:

y =mx + b

This is called the slope-intercept form.

The slope is

m =  -  \frac{2}{3}

and the y-intercept is 3.

The correct answer is A.

In a situation where the line is not given in the slope intercept form, then you must rewrite in this form before comparing.

Tom has 12 reports to file. If each report takes an average of 45 minutes to file, how long will it take him to file 75% of them
Jobisdone [24]

Alright, lets get started.

One report takes to file an average of = 45 minutes

Means 12 reports takes to file time = 12 * 45 = 540 minutes

12 reports filing total time = 540 minutes

We are asked to find time to file 75 % of them.

Which means 75 % of 540

= 540 * 75/100

= 540 * 0.75

= 405 minutes

We could convert it into hrs dividing with 60.

405 / 60 = 6.75 hrs

Means it will take 6.75 hrs to file 75% of them: Answer

Hope it will help :)
