30 points. a metallic paperweight in the shape of a rectangular prism measures 9 centimeters by 4 centimeters by 4 centimeters and has a mass of 1267.2 grams. what is the density of the paperweight? enter your answer in the box.

8.8

Step-by-step explanation:

Density = Mass / Volume

Volume = 9 × 4 × 4  = 144

Mass = 1267.2

Density = 1267.2 / 144 = 8.8

They're giving you the answer right in the question!
Think about the slope formula: y2-y1/x2-x1. Surely you know that the answer to a subtraction question is referred to as the difference! Since, they said the difference between the two x-coordinates is 3 and difference between the two y-coordinates is 6, you would just plug those right into the slope formula! 6/3 equals 2. 
The slope of the line that passes through the points would be 2!
