How do you find the y-intercept of the graph of the equation?
Set 'x' equal to zero, and solve the remaining equation for 'y'.
How do you graph 5x-4y equals -15?
You are solving for x and y. If x is set equal to 1 and y is set equal to 4, then you have 5-20=-15. You can graph this by placing a point on the graph corresponding to x and y. That is, on the x axis you would go over 1 and on the y axis you would go up 5. Now if x is set equal to 5, then that is 25, so y must be set equal to 10. This is 25-40=-15. Then on the same graph, you go over 5 on the x axis and go up 10 on the y axis. Now you can draw a line between the two. All you have to do now is solve the equation for another set of numbers, and then put that point on the graph. With three points, you have sufficient information.
Are a polynomial's factors the values at which the graph of a polynomial meets the y-axis?
Not quite. The polynomial's linear factors are related - not equal to - the places where the graph meets the x-axis. For example, the polynomial x2 - 5x + 6, in factored form, is (x - 2) (x - 3). In this case, +2 and +3 are "zeroes" of the polynomial, i.e., the graph crosses the x-axis. That is, in an x-y graph, y = 0.
What is a piecewise function whose graph resembles a set of stair steps?
One such function is [ Y = INT(x) ]. (Y is equal to the greatest integer in ' x ')
How do you make a x y graph?
Just label one axis x and the other axis y. Voila!! x y graph!
Y 2x plus 3 graph?
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
What does y-x-2 look like on a graph?
You could not graph (y-x-2) because it has no equal sign in it. In order to graph an equation, there must be a value that the numbers and variables are equal to. (e.g. y=2x+3)
What is a function rule?
how you get x to equal y. it is usually in a graph
What does the y intercept have to do with the graph?
The y-intercept on the graph shows where the graph crosses the y-axis. The value is always the value of y at that point, because x is always equal to zero.
What describes how to translate the graph y x to obtain the graph of y x - 6?
To translate the graph y = x to the graph of y = x - 6, shift the graph of y = x down 6 units.
When graphing an inequality with the symbol less than or equal to what is drawn?
if you have y <= f(x), then graph the function y = f(x) with a solid line, then shade everything below that graph.
How do you find the y-intercept of the graph of the equation?
Set 'x' equal to zero, and solve the remaining equation for 'y'.
How do you graph x is greater than or equal to y?
Take a blank graph with 'x' and 'y' axes on it. Draw a 45-degree line on the graph. The line goes through the origin, and from the origin, it goes down-left and up-right. The slope of the line is 1, and its equation is y=x. The region "y is greater than or equal to x" is every point on that line, plus every point on the side above it (to the left of it).
What is x intercept defined as?
The x-intercept is the point at which a graph or function intersects the x-axis. It is the value of x when y is equal to zero on the graph.
What is the opportunity cost formula?
opportunity cost of x is equal to y over x. The answer then becomes the slope for the graph.
Sketch the graph for equation x plus y equals 5?
It's equal to -X + 5 = Y (1, 4) (5, 0)
