Describe, step-by-step how to find the slope of a line through two points

Mathematics
1 answer:
Amanda [17]3 years ago
6 0

Step One: Identify two points on the line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

Step Three: Use the slope equation to calculate slope.

The equation used to calculate the slope from two points is: m= y2 - y1 / x2 - x1

Example

Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?

Step One: Identify two points on the line.

In this example we are given two points, (15, 8) and (10, 7), on a straight line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).

Step Three: Use the equation to calculate slope.

Once we've completed step 2, we are ready to calculate the slope using the equation for a slope:

Answer:

a= 1%

b= 0.1%

c= 0.1875% probably have to round

Step-by-step explanation:

a= 2/2= 1

B= 1/10=0.1

c= 1.5/8= 0.1875

Plz help me. I forgot how to do this XD
nirvana33 [79]
This question has to do with making an approximation based on the diagram of the angle. Angle KLM is an obtuse angle meaning it is larger then 90° but is also less than 180°. The only choices that lie within this range are choices B and D. However, it is safe to assume that angle KLM is closer to 180° than to 90° based on the diagram, therefore the answer must be choice B.

I hope this helps.

Paul wants a bike that cost $400. If he had saved 60% of this amount, how much had he saved.
enyata [817]
Hey!


To solve this problem, we'll first start by creating an equation.

<em>Our Created Equation :
</em>
\frac{400 x 60}{100}

Now we'll solve it step by step to find the answer.

So we should begin by multiplying the to portion of our fraction.

<em>400 x 60 = 24,000</em>

Next, we divide our answer by 100, since that is the next step to our equation.

<em>24,000 ÷ 100 = 240</em>

So, our answer is...

<em>Paul has already saved</em>  $240.00  <em>of the $400.00 he must pay for a new bike.</em>

Hope this helps!
