The graph of a straight line contains two points, A and B. At point A on the line, x equals 3 and y equals 5. At point B on the line, x equals 10 and y equals 9. What is the slope of this line? (Round your answer to 2 decimal places.)

Respuesta :

Answer:

0.57

Explanation:

The slope of a line is defined as

[tex]\text{slope}=\frac{\text{rise}}{\text{run}}[/tex]

Now the rise is the difference in the y-coordinates between two points and the run is the difference in the x-coordinates.

The two points we are given are

From the sketch above we see that

[tex]\text{rise}=9-5=4[/tex][tex]\text{run}=10-3=7[/tex]

therefore, the slope is

[tex]\text{slope}=\frac{\text{rise}}{\text{run}}=\frac{4}{7}[/tex][tex]\text{slope}=\frac{4}{7}[/tex]

Which is our answer!

But we are asked to give the answer in a decimal form rounded to two decimal places.

Therefore, we divide 4 by 7 and get

[tex]4\div7=0.571428\ldots[/tex]

rounding to the nearest 2 decimals gives

[tex]4\div7=0.57[/tex]

Hence,

[tex]\boxed{\text{slope}=0.57}[/tex]

which is our answer!
