What are the slope and y-intercept of the linear function graphed to the left? slope: –2; y-intercept: 2 slope: ; y-intercept: 1

Anon25 [30]

Let

$A(0,1)\\ B(2,0)$

we know that

The y-intercept is the y-coordinate of the point when the value of x is equal to zero

the y-coordinate of the point A is the y-intercept

$y=1$

<u>The answer part a) is</u>

The value of y-intercept is $1$

<u>Part b)</u> Find the slope m

we know that

the value of the slope is equal to

$m =\frac{(y2-y1)}{(x2-x1)}$

Substitute the values

$m =\frac{(0-1)}{(2-0)}$

$m =-\frac{1}{2}$

therefore

<u>the answer Part b) is</u>

The value of the slope is equal to $-\frac{1}{2}$

<u>The general answer is</u>

The slope is $-\frac{1}{2}$

The value of y-intercept is $1$

Answer:

0.08 cubic feet.

Step-by-step explanation:

You have a small marble statue of Mozart that is 10 inches tall and is made of 16 cu. inches of marble.

The original statue in Vienna is 7 feet tall.

First we will convert this to inches as one relation is given in inches.

1 feet = 12 inches

7 feet = $12\times7=84$ inches

Let the amount of marble used for 84 inches statue be = x

We can relate both the conditions in the following way:

$\frac{10}{16} =\frac{84}{x}$

$10x=16\times84$

$10x=1344$

x = 134.40 cubic inches

Now, 1 cubic inch = $\frac{1}{1728}$ cubic foot

So, 134.40 cubic inches = $\frac{134.40}{1728}$ cubic foot

= 0.0777 cubic feet rounding to 0.08 cubic feet.
