follow these steps:
- Realize that the circle is centered at the origin (no h and v) and place this point there.
- Calculate the radius by solving for r. Set r-squared = 16.
- Plot the radius points on the coordinate plane.
- Connect the dots to graph the circle using a smooth, round curve.
To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.
The graph of y = b is a horizontal line passing through the point (0, b) on the y-axis. To graph an equation of this form, such as y = 4, plot the point (0, b) on the y-axis and draw a horizontal line through it (see Example 4). If the equation is not in the form y = b, solve the equation for y. Vertical Lines: x = a.
Explanation: Since there is no x then the line is horizontal and has a slope of 0. Go to 4 on the y-axis and just draw a horizontal line that runs both through the negative and positive sides.
The answer is no. Since y has to be 4, then it can never equal 0, which is the criteria of an x-intercept. Also, think about it, if we have a horizontal line that crosses the y-axis at 4, it will never ever cross the x-axis. So, some points that we can use are (0, 4), (1, 4) and (2, 4).
It is a relationship, but it is not a function, for these reasons: Value "3" in X has no relation in Y. Value "4" in X has no relation in Y. Value "5" is related to more than one value in Y.
Yes it is a function.Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. The horizontal line goes through 4 on the vertical y axis.
To graph the absolute value, you need to know where the vertex is, so the numbers will be going down, then turn and start going back up, or going up and then turn and start going down, the middle point will be the vertex and should be the center point of the table.
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a computer. In the past, sometimes mechanical or electronic plotters were used.
On a graph, draw two lines perpendicular to each other, intersecting at 0. The horizontal line is x-axis and vertical line is y-axis. Along the horizontal axis, choose the uniform width of bars and uniform gap between the bars and write the names of the data items whose values are to be marked.
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
