How the solution of a linear system with two equations is represented by the point where the graphs of the two equation intersect?
The first graph consists of all points whose coordinates satisfy the first equation.The second graph consists of all points whose coordinates satisfy the second equation.The point of intersection lies on both lines so the coordinates of that poin must satisfy both equations.
How do you determine if a certain point lies on a given line by just having the coordinates for the point and the equation of the line?
Substitute the x coordinate into the equation for x and calculate y. If the formla gives the same y value as the coordinates, the point is on the line. If it is diffent, it is not on the line.
What quadrant is 0 -3 in?
(0, -3) is not in any quadrant. I lies on the border between two quadrants. Because zero is not positive or negative, it cannot be defined as in a quadrant
When the first number in an ordered pair is 0 where is the point located?
The first number in an ordered pair (of rectangular coordinates) is the distance from the origin along the x- axis. If the number is 0, then any point having this coordinate must lie on the y-axis. If the second number is 0 then the point is at the origin (0,0). If the second number is positive then the point lies on the y-axis above the origin. If the second number is negative then the point lies on the y-axis below the origin.
Express the function 120 degree as function of an acute angle?
Example: Express sin 120⁰ as a function of an acute angle (an angle between 0⁰ and 90⁰).Solution:Each angle θ whose terminal side lies in quadrant II, III, or IV has associated with it an angle called the reference angle, alpha (alpha is formed by the x-axis and the terminal side).Since 120⁰ lies on the second quadrant, then alpha = 180⁰ - 120⁰ = 60⁰.Since sine is positive in the second quadrant, sin 120⁰ = sin 60⁰.Example: Express tan 320⁰ as a function of an acute angle.Solution:Since 320⁰ lies on the fourth quadrant, then alpha = 360⁰ - 320⁰ = 40⁰.Since tangent is negative in the fourth quadrant, tan 320⁰ = -tan 40⁰.
Where does a point with both the x- and y-coordinates positive lie?
It lies in quadrant I.
What must be true about the coordinates of any point that lies in the third quadrant?
Both coordinates are negative in this case.
(-23) lies in quadrant?
The coordinates of (-1, 3) lie in the 2nd quadrant on the Cartesian plane
Why not every point lies in quadrant?
Well, it could lie in Quadrant 1,2,3,4.
How do you give the coordinates of a point that lies in the interior of the angle?
The coordinates of a point are in reference to the origin, the point with coordinates (0,0). The existence (or otherwise) of an angle are irrelevant.
How do you determine if a point lies on the same line?
A point lies on a line if the coordinates of the point satisfy the equation of the line.
Identify the quadrant in which the point x y lies if x 0 and y?
If x = 0 then the point is on the y-axis and so it not in any quadrant.
What line does the point (-16) lie on?
If you mean the point of (-1, 6) then it lies in the 2nd quadrant on the Cartesian plane
What quadrant is -6 -5 lies in?
-1
In what quadrant is 0-5?
(0-5) lies in First Quadrant
What quadrant does -135 degrees?
-135 degrees lies in quadrant 3.
What are the quadrant angles?
Quadrant angles are the angle lies in different quadrants. The angles which lie between 0° and 90° are said to lie in the first quadrant. The angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant and angles between 270° and 360° are in the fourth quadrant Quadrant angles are the angle lies in different quadrants. The angles which lie between 0° and 90° are said to lie in the first quadrant. The angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant and angles between 270° and 360° are in the fourth quadrant
