1a. what is the slope. 1b. what is the y- intercept 1c. write the equation. PLEASE HELP IM DOING HOMEWORK AND ITS 1:00am

Sedaia [141]

the slope is 1 cos its goin ovr one, up one

y-int is (0,3) or jus strait up 3 cos thts where it crosses the y

iiiif you write it using y=mx+b,, m is the slope n b is the y int so itd jus be: y=x+3

SUPPOSE 3 FRIENDS WANT TO SHARE 16 POSTERS EQUALLY. FOR THIS SITUATION, WHY DOES THE QUOTIENT 5 R1 MAKE MORE SENSE THAN THE QUOT

Vikentia [17]

Because normally you don't cut posters into thirds. You keep them as whole numbers therefore fractions make no sense

A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant prod

Archy [21]

Answer:

$y = -\frac{1}{3}m + 41$

Step-by-step explanation:

Linear equation:

A linear function has the following format:

$y = mn + b$

In which m is the slope and b is the y-intercept.

When she plants 30 stalks, each plant yields 31 oz of beans. When she plants 36 stalks, each plant produces 29 oz of beans.

This means that these two points belong to the line: (30,31), (36,29).

Finding the slope:

When we have two points, the slope is given by the change in the output divided by the change in the input.

Change in the output: 29 - 31 = -2

Change in the input: 36 - 30 = 6

Slope:

$m = \frac{-2}{6} = -\frac{1}{3}$

Thus

$y = -\frac{1}{3}m + b$

Finding b:

We take one of the points and replace on the equation.

(30,31) means that $m = 30, y = 31$ . Thus

$y = -\frac{1}{3}m + b$

$31 = -\frac{1}{3}(30) + b$

$31 = -10 + b$

$b = 41$

Thus

$y = -\frac{1}{3}m + 41$
