Answer:

M = -2

b = -10

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

m = (-8 -0)/(-1- -5)

   = (-8-0)/(-1+5)

    = -8/4

    = -2

We now want to find the y intercept

y = mx+b is the slope intercept form of the equation

y = -2x+b

Using the point (-5,0)

0 = -2(-5) +b

0 = 10+b

Subtract 10 from each side

-10 = 10-10+b

-10 =b

The y intercept is -10

y= -2x-10

Answer:

1) slope: -2

2) y-intercept: -10

Equation:

y = -2x - 10

Step-by-step explanation:

1) slope: (-8 - 0)/(-1 - -5)

= -8/4 = -2

2) y = -2x + c

0 = -2(-5) + c

c = -10

Equation:

y = -2x - 10

One day at a supermarket, 258 fruits were sold in the morning, and 5/6 of the number of fruits sold in the morning were sold in
astra-53 [7]

Answer:

258 fruits.

Step-by-step explanation:

We have been given that one day at a supermarket, 258 fruits were sold in the morning, and 5/6 of the number of fruits sold in the morning were sold in the afternoon.

So the fruits sold in the afternoon will be 5/6 of 258.

\text{The number of fruits sold in afternoon}=\frac{5}{6}\times 258

\text{The number of fruits sold in afternoon}=5\times 43

\text{The number of fruits sold in afternoon}=215.

Further, we are told that the number of fruits sold in the next afternoon increased by 20% compared to the number of fruits sold in the afternoon the previous day.

So the number of fruits sold in the next afternoon will be:

\text{The number of fruits sold in next afternoon}=215+(\frac{20}{100}\times 215)

\text{The number of fruits sold in next afternoon}=215+(0.20\times 215)

\text{The number of fruits sold in next afternoon}=215+43

\text{The number of fruits sold in next afternoon}=258

Therefore, 258 fruits were sold in the afternoon the next day.
