David > Chris
Chris < Annie
Annie = Sarah
Sarah < David
David is out since he is taller that Chris.
Anne is out since she is taller than Chris.
Sarah is out since Anne and Sarah are the same height.
Chris is the shortest, because he is shorter than Annie and Sarah, while Sarah and Annie are shorter than David, but Chris is shorter than Annie so Sarah applies too, Chris is shorter than Anne and Sarah.
Shortest ---> Tallest:
Chris, Anne, Sarah, David

This is a problem involving comparisons; when you have a problem like that, is a good idea to compare two things at the time.

Let's compare our subjects

- Since David is taller than Chris and Chris is shorter than Anne, Anne is shorter than David (or David is taller than Anne).

- Since Chris is shorter than Anne and Anne is as tall as Sarah, Chris is also Shorter than Sarah.

- Since Sarah is shorter than David and Chris is Shorter than Sarah, Chris is also shorter than David.

From the first and third sentences we can infer that Chris is shorter than David. From the second sentence we can infer that Chris is shorter than Anne. From the second sentence we can infer that Chris is shorter than Sarah. Chris is shorter than everyone!

We can conclude that the shorter person is Chris.

In addition, we can follow a similar pat to discover who is the tallest:

We already know that the shorter person is Chris; since Anne and Sarah are taller than David and David is taller than Anne and Sarah, David is the tallest person. Sarah and Anne tie in second place.

Write in slope intercept form an equation of the line that passes through (-2,5),(-1,1)
Juliette [100K]

Answer:

y=-4x-3

Step-by-step explanation:

Hi there!

We are given the following two points: (-2,5) and (-1,1)

We want to write the equation of the line that passes through these two lines in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, let's find the slope

The formula for the slope (m) calculated from 2 points is \frac{y_2-y_1}{x_2-x_1}, where (x_1, y_1) and (x_2, y_2) are points

We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion

x_1=-2\\y_1=5\\x_2=-1\\y_2=1

Now substitute into the formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{1-5}{-1--2}
Simplify

m=\frac{1-5}{-1+2}

Subtract

m=\frac{-4}{1}

Divide

m=-4

Now substitute -4 as m into the equation:

y=-4x+b

Now we need to find b

As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.

Taking (-2,5) for example:

Substitute -2 as x and 5 as y:

5=-4(-2)+b

Multiply

5=8+b

Subtract 8 from both sides

-3=b

Substitute -3 as b.

y=-4x-3

Hope this helps!
