The period is the length of x over which the equation repeats itself. In this case, y=sin x delivers y=0 at x=0 at a gradient of 1. y next equals 0 when x equals pi, but at this point the gradient is minus 1. y next equals 0 when x equals 2pi, and at this point the gradient is 1 again. Therefore the period of y=sinx is 2pi.
Since no points were given, for any point (x,y), plug the x and y values of the point into the equation. If you get a contradiction, ie 5=3 or something similar, then the point does not lie on the graph.
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2). However, it does not seem likely that the point can be on that line.

However, the question looks as if it might be a linear equation: an equation of a straight line. If that is the case then there are infinitely many solutions. The coordinates of each point on the line represents a solution.
Add 2.9 to both sides. y = 8.2

In the Cartesian plane, each point has two coordinates. Point 6 and point 8 are not sufficiently uniquely defined.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
There are infinitely many ordered pairs - each pair representing a different point on the infinite line described by the equation.
You find the gradient of the curve using differentiation. The answer is 0.07111... (repeating).
3x-4y-6 = 0

Thanks to the limitations of the browser, it is not possible to read the equation of the line. Perhaps you could use words - such as "plus", "minus" and "equals" rather than the symbols and resubmit.
No line described, but here is the point slope form. Y - Y1 = m(X - X1) =============
A linear equation is the equation of a line and that consists of an infnite number of points. What you have, in x = -4 and y = -1/3, is a single point. A single point is not a line and so there cannot be a linear equation (suitable for a line) to represent a point.
Do you mean 0.4y+0.6y = 3y -36? If so then: y = 18
