You can calculate the slope of a line by thinking of a simple system, rise over run.

You do this calculation by finding two places where the line crosses over a point.

You then start at your first point and count up or down to the height of the second point, this is your RISE

After, you go from your second point and count left or right towards your first point. this is your RUN


If we use this system, we count up 1 unit for our rise and count 5 units for our run, rise over run the slope would be 1/5.


Your slope is 1/5

6. Solve for x. Show all work and round to the nearest hundredth if necessary.<br> 20<br> 55°
tigry1 [53]

Answer:

x ≈ 11.47

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos55° = \frac{adjacent}{hypotenuse} = \frac{x}{20} ( multiply both sides by 20 )

20 × cos55° = x , then

x ≈ 11.47 ( to the nearest hundredth )
