Answer:

Step-by-step explanation:

Subtract the "Y" values from the ordered pairs -1 - (-7)= 6

Subtract the "X" values from the ordered pairs 1-5 = -4

Remember slope is rise over run or y over x so the answer is -6/4 or -3/2 reduced

I always bring my negative to the top after I finish solving

Since you didn't provide the choices your answer is either going to be 3/-2 or -3/2 depending if your teacher makes you bring the negative to the top

Answer:

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

Each year lizzy e's school purchases students agenda books, which are sold in the school store.This year, the school purchased 3

In order to make back the money they spent ($1,137.50) plus $1500, they want to make $1137.5+1500=2637.5$ $2,637.50 total.

They want to make this amount by selling 350 agendas, so divide the amount they want to make by 350 to find the amount per book:
$2637.5/350=7.54$
I rounded the answer to the nearest hundredth because the hundredth is the smallest amount we have in USD (the penny.)
So they need to charge at least $7.54 to make back their money plus $1500.

Hope I helped, and let me know if you have any questions :)

Answer:

Relation

Explanation:

The definition of a relation is just a set of ordered pairs.

A function is a relation in which each domain element is paired with exactly one range element.

It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.

I hope that helps a bit
