The correct answer is D ) (-2, 1) and (3, -2)

In order to find this, we must find the full value of the equation using one of the points and the slope. This will allow us to find the y-intercept. We'll use the (-2, 1) point to start.

y = mx + b

1 = -3/5(-2) + b

1 = 6/5 + b

-1/5 = b

This y-intercept gives us the overall equation of y = -3/5x - 1/5. Now we can try the other point in the equation to see if it works as well.

y = -3/5x - 1/5

-2 = -3/5(3) - 1/5

-2 = -9/5 - 1/5

-2 = -10/5

-2 = -2 (TRUE)

Since this works in the equation, we know that D is the correct answer.

You and your friend each purchase an equal number n of magazines. Your magazines cost $1.50 each and your friend's magazines cos
slava [35]

Given:

You and your friend each purchase an equal number n of magazines.

Your magazines cost = $1.50 each

Your friend's magazines cost = $2 each

Total cost = $10.50

To find:

The equation to find number of magazines you purchased.

Solution:

Your magazines cost = $1.50 each

Your friend's magazines cost = $2 each

Number of magazines purchased by you and your friend = n

Total cost = 1.50n+2n

It is given that total cost is $10.50.

1.50n+2n=10.50

3.50n=10.50

Divide both sides by 3.50.

n=\dfrac{10.50}{3.50}

n=3

Therefore, required equation is 1.50n+2n=10.50 and the number of magazines purchased by you is 3.
