Answer:
The types of slope for each pair are:
(2, 4) and (5, 1) => Negative
(3,5) and (-1,2) => Positive
(-7, 8) and (-7,0) => Undefined
(6.-3) and (4, -3) => Zero
Step-by-step explanation:
We will find the slope of each line to check the type of slope.
Slope is given by the formula:
Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point
Now,
<u>(2, 4) and (5, 1)</u>
The slope is negative.
<u>(3,5) and (-1,2)</u>
The slope is positive
(-7, 8) and (-7,0)
division by zero makes the slope undefined.
(6.-3) and (4, -3)
The slope is zero
Hence,
The types of slope for each pair are:
(2, 4) and (5, 1) => Negative
(3,5) and (-1,2) => Positive
(-7, 8) and (-7,0) => Undefined
(6.-3) and (4, -3) => Zero
Answer:
68°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...
Cos = Adjacent/Hypotenuse
This means ...
cos(B) = a/c
B = arccos(1/√7) ≈ 68°
