Please explain how you find the slope of a graph? Please explain with photos.
gogolik [260]

☁️ Answer ☁️

Here's what I found:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Check your result using the slope calculator.

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.

A professor grades students on four tests, a term paper, and a final examination. Each test counts as 15% of the course grade. T
alina1380 [7]

Answer:

The Alans's average for the course is 84.5

Step-by-step explanation:

We are given

There are 4 tests, A Term paper and a Final examination.

Score = 92, 78, 82, 90.

Term paper score = 80

Final examination score = 86

Weighted mean = ∑ w.f/∑w

     also the sum of all the weights is 100% = 1

weighted mean = 15%*92 + 15%*78+15%*82+15%*90+20%*80+20%*86/1

                         = 51.3 + 33.2

                         =  84.5

Therefore the Alans's average for the course is 84.5

Find the slope of the line that passes through (3, 2) and (7,5)
Bas_tet [7]

Answer:

\frac{3}{4}

Step-by-step explanation:

Slope is equal to the change in y over the change in x.

m =  \frac{change \: in \: y}{change \: in \: x}

The change in x is equal to the difference in x-coordinates, and the change in y is equal to the difference in y-coordinates .

m =  \frac{y2 - y1}{x2 - x1}

Substitute in the values of x and y into the equation to find the slope.

m =  \frac{5 - (2)}{7 - (3)}

Simplify.

m =  \frac{3}{4}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>3</u><u>/</u><u>4</u><u>.</u>

What are the solutions to 16x -12x+0=54?
Citrus2011 [14]

Answer:

x = 13 1/2

Step-by-step explanation:

16x -12x+0=54

combine like terms

4x + 0 = 54

4x = 54

divide each side by 4

4x/4 = 54 /4

x = 54/4

x = 13 2/4

x = 13 1/2
