Hello!

First of all we solve for the slope as seen below.

\frac{3+5}{-6+4} = -\frac{8}{2} = -4

Our slope is -4.

Now we substitute a point from our equation into slope intercept form, along with the slope. Then we solve for b. We will use (-4,-5)

-5=-4(-4)+b
-5=16+b
b=-21

Our final equation is shown below.

y=-4x-21

I hope this helps!

Evaluate the following expression:<br> 62 − 7(8 + 6 − 32)
Alex Ar [27]

Answer:

188

Step-by-step explanation:

<u>Step 1:  Distribute</u>

62 − 7(8 + 6 − 32)

62 + (-7 * 8) + (-7 * 6) + (-7 * -32)

62 + (-56) + (-42) + (224)

<u>Step 2:  Combine the first two numbers</u>

(62 - 56) - 42 + 224

6 - 42 + 224

<u>Step 3:  Combine the next two number</u>

(6 - 42) + 224

-36 + 224

<u>Step 4:  Combine the last two number</u>

-36 + 224

188

Write an equation to model this proportional relationship, where x represents the length of the rectangle and y represents the w
Kay [80]

When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle.

x\propto  \frac{1}{y}

We know that the area of a rectangle is given by the product of the length and width of the rectangle.

Area = Length*Width

In this given problem,

The length of the rerectanglctangle is represented by x

and the width of the rectangle is represented by y

If the area of the rectangle is represented by A now.

So by the formula,

A = x*y

When A is constant then,

x = A/y

\therefore x \propto \frac{1}{y}

So from the above calculation we can conclude that about relation between length and width that,

"When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle."
