What is the equation of the line in the slope - intercept form

Oxana [17]

Answer:

y = -2x+16

Step-by-step explanation:

The line has a y intercept at 16 (This is where it crosses the y axis)

The slope is found by using

m = (y2-y1)/(x2-x1)

We have two point (0,16) and (8,0)

m = (0-16)/ (8-0)

= -16/8

= -2

We can use the slope intercept form of a line

y= mx+b where m is the slope and b is the y intercept

y = -2x+16

1)The base of a triangular prism is a right triangle with a base of 20 feet and a height of 120 inches. The height of the prism

ivanzaharov [21]

Answer:

(1)750 cubic feet

(2)8 Times

Step-by-step explanation:

Question 1

Dimensions of the Right Triangular Base

Base = 20 feet
Height= 120 inches = 10 feet

Base Area of the Prism

$=\dfrac12 \times 20 \times 10\\=150$ square feet$

Height of the Prism = 5 feet

Volume of the Prism = Base Area X Height

= 150 X 5

=750 cubic feet

Question 2

Jake's Box

Length: 12 inches
Width: 4 inches
Height: 8 inches

Volume = 12 X 4 X 8 =384 cubic inches

Havana's box

Havana has a shipping box similar to Jake's box, but each dimension is half as long.

Therefore:

Length: 12/2=6 inches
Width: 4/2=2 inches
Height: 8/2=4 inches

Volume = 6 X 2 X 4 =48 cubic inches

Now:

384/48=8

Therefore, the volume of Jake's box is 8 times larger than Havana's box.
