Which side of the graph is positive and negative?
A way to remember this is to think about the numbers are on the x-axis. Going to the right of the origin are the positive values, and going to the left of the origin are the negative values.
What is the negative side of a graph?
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
Which quadrants on a graph are negative?
The Cartesian plane is divided into four quadrants. In Quadrant I, both the x– and y-coordinates are positive; in Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative.
How do you tell if a polynomial graph is positive or negative?
If the degree of the polynomial is even and the leading coefficient is positive, both ends of the graph point up. If the degree is even and the leading coefficient is negative, both ends of the graph point down.
What does a negative graph look like?
Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls. We will learn that “price” and “quantity demanded” have a negative relationship; that is, consumers will purchase less when the price is higher. Graphically, the line is flat; the rise over run is zero.
What does a positive line look like on a graph?
If a line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
How do you tell if a cubic graph is positive or negative?
If they start “down” (entering the graphing “box” through the “bottom”) and go “up” (leaving the graphing “box” through the “top”), they’re positive polynomials, just like every positive cubic you’ve ever graphed. But If they start “up” and go “down”, they’re negative polynomials.
