The slope intercept form of the equation of a line is given as:
y = mx + c
where m = the slope of the line
c = the y - intercept of the line
1) Two line are parallel if they have the same slope
That is:
2) Two equations are perpendicular if the slope of one is the negative inverse of the other.
3) Two equations are coincidental if they have the same slope and the same y intercept
Answer:
The period of the function is
Step-by-step explanation:
The graph completes one cycle in the interval .
The length of this interval is .
The graph completes another cycle within the interval .
The length of this interval too is .
This means that after every 10 units, the graph repeats itself. Therefore the period is 10.
The graph is a sine function because it is symmetric about the origin.
Its equation is .
