Step-by-step explanation:

Convert the equation to the slope-intercept form (y = mx + b):

-x-2y=-10 add x to both sides

-2y=x-10 divide both sides by (-2)

$y=-\dfrac{1}{2}x+5$

Choose any three values of x and calculate the values od y:

for x = 0

$y=-\dfrac{1}{2}(0)+5=0+5=5\to(0,\ 5)$

for x = 4

$y=-\dfrac{1}{2}(4)+5=-2+5=3\to(4,\ 3)$

for x = 10

$y=-\dfrac{1}{2}(10)+5=-5+5=0\to(10,\ 0)$

No. of Persons= 16

Step-by-step explanation:

There was a one phone line

Average no of people calling = 60 in one hour

% of all callers at most can get busy signal

Probability < 0.6

Probability for less than 1 person on hold = 0.2642

No of persons = 0.2642(60)

= 15.852 or 16

16 persons in hour the company is able to put on hold
