Use the slope formula to solve this.

m = y₂ - y₁ / x₂ - x₁
So since the points are (4, 1) and (7, -2) here's how you'd work it out:

Substitute the variables for the corresponding number.
m = -2 - 1 / 7 - 4
Solve the top and bottom.
m = -3 / 3
Now divide.
m = -1

So your answer is B.

Solve for x. <br> 2(x-2)= 6x + 2 -2(-2x - 4)
Lena [83]

Answer:-7/4

Step-by-step explanation:

2(x-2)=6x+2-2(-2x-4)

Open brackets

2x-4=6x+2+4x+8

Collect like terms

-4-2-8=6x+4x-2x

-14=8x

Divide both sides by 8

-14/8=8x/8

-7/4=x

x=-7/4

What is the rule for finding the coordinates of an image reflected over the line y=-x
joja [24]
You can find the coordinates of any graph by using a coordinate table, which looks as so in the chart provided below.

What you do is you, put in the letter x and then put what y is equal to in the second box. You plug in any number for x and you solve in order to find the y coordinate. Once you do, for example for plugging in -1 into x you get 1. So your coordinate would be (-1,1).

The question is incomplete:

Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexico, he had 100 pesos left.

How much will he receive when he exchanges these pesos for dollars?

Answer:

9 dollars

Step-by-step explanation:

To find the amount that Levant will receive when he exchanges these pesos for dollars, you can use a rule of three using the information provided:

270 dollars   →  3,000 Mexican pesos

        x           ←  100 Mexican pesos

x=(270*100)/3,000=9 dollars

According to this, the answer is that he will receive 9 dollars.
