Point slope form is y - y1 = m(x-x1)
So,
y - (-1) = 2(x - 1)
y + 1 = 2x -2 or y + 1 = 2(x -1)
Hope this helps :)
36.3 because the digit in the hundredths place is not 5 or greater
You would have to do distribution you would do 5(2x) which would give you 10 and 5(10) which gives you 50 so your equation would be -60=10x+50 then you would subtract 50 from both sides which would give you -110 your equation would be -110=10x divided 10 on both sides and your answer would be x=-11
The answer is: 
The explanation for this answer is shown below:
1. By definition, the amount of second required for the pendulum to move from its resting position and return, is the period.
2. As you can see in the graph attached in the exercise, the wave interval is repeating every two units of x (or
).
3. Therefore, the period is
.
