what is the equation of a line through (-1 4) and (1 -2)

Answer: y=-3x+1

Step-by-step explanation:

1. Use the formula [tex]\frac{y2-y1}{x2-x1}[/tex]

2. Subsitute:

[tex]\frac{4-(-2)}{-1-1}[/tex] => [tex]\frac{6}{-2}[/tex]

3. Solve for m in the equation y=mx+b:

m=-3(from step above)

4. y+2=-3(x-1)

=> y+2=-3x+3 => y=-3x-1

Have a nice day! :D

In this experiment, you will be using two different coins as a simulation for a real-world compound event.

Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.

What is the theoretical probability that the family has two dogs or two cats?

Describe how to use two different coins to simulate which two pets the family has.

Flip both coins 50 times and record your data in a table like the one below.

Based on your data, what is the experimental probability that the family has two dogs or two cats?

If the family has three pets, what is the theoretical probability that they have three dogs or three cats?

How could you change the simulation to generate data for three pets?

A rectangle has vertices at (Negative2, 11), (Negative2, 4), (6, 11), and (6, 4). Pablo says the area of the rectangle is 49 square units and his work is shown below.

Steps
Pablo’s Work
Step 1
Base: StartAbsoluteValue negative 2 EndAbsoluteValue + StartAbsoluteValue 6 EndAbsoluteValue = 8
Step 2
Height: 11 minus 4 = 7
Step 3
Area: 8 times 7 = 49 square units

Where, if at all, did Pablo first make a mistake finding the area of the rectangle?
Step 1
Step 2
Step 3
no mistake
