Find the slope of the line that passes through (95, 2) and (-2, 95).
adoni [48]

Answer:

Slope is -93/97

Step-by-step explanation:

To find slope subtract the y's and put that answer in top of a fraction. Then subtract the x's and put that on the bottom of the fraction. If its a smaller number on top and bigger number on the bottom, that is a proper fraction. If the bigger number is on top then it is an improper fraction. If it divides evenly, then the answer will just be a whole number (what the questions calls an integer) All these answers can be positive or negative.

***BUT, you have to start the subtractions with the same point!!!

Let's start with (-2, 95) in front, for both subtractions. (But it could be either point, the answer comes out the same)

Subtract y's: 95-2 is 93.

Subtract x's: -2 - 95 is -97

The slope is 93/-97 it is a proper fraction.

We can put the negative sign in front instead of at the bottom, it looks better.(and is the same)

Slope is -93/97

A student is working on a project for which he records the revolutions per minute (rpm) for a small electric motor as he increas
Ber [7]

Answer:

See below ↓

Step-by-step explanation:

The relation is :

  • Let y = Motor Speed and x = Voltage
  • y = 25x

<u>Title</u> : Variation of Motor Speed with Applied Voltage

<u>x-axis label</u> : Voltage (volt)

<u>y-axis label</u> : Motor speed (rpm)

As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.

Rus_ich [418]

A. It is a parallelogram so, the formula is just simple base × height; 16cm × 9cm = 144cm²

B. It is a trapezoid so, the formula is base1 + base2 ÷ 2 × height; 25cm+ 44.67cm= 69.67cm ÷ 2 = 34.835cm × 20cm= 696.7cm²

C and D are irregular shapes - the diagram will show you how to do them...
