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.
The y- axis in the vertical axis and the x-axis in the horizantal axis
In the coordinate plane, the x-axis is horizontal, and the y-axis is vertical.
The convention for an x-y graph is as follows: y | | |_____ x where the x-axis is horizontal and the y-axis is vertical.
The x-axis is the horizontal axis on a graph. The y-axis is the vertical axis on a graph.
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.

None, it touches it at x = -3.For a quadratic y = ax2 + bx + c, it will meet the x-axis (y = 0) either 0, 1 or 2 times dependent on: b2 - 4ac. If b2 - 4ac is:> 0 the line meets the x-axis twice, so crosses it twice= 0 the line meets the x-axis once, so it does not cross it but only meets it.< 0 the line does not meet the x-axis at all, so cannot cross it.for y = x2 + 6x + 9:b2 - 4ac = 62 - 4 x 1 x 9= 36 - 36= 0so the line meets the x-axis once, but does not cross it - all the values of y are greater than, or equal to zero, but never negative.
The y- axis in the vertical axis and the x-axis in the horizantal axis
You know that y = 2x - 3, so to draw the graph: (a) You work out where this equation meets the horizontal axis of the graph and put a mark there. (b) You also work out where it meets the vertical axis of the graph and put a mark there. You then draw a straight line through the two points which carries on on either side. For (a) the equation meets the horizontal axis when y = 0. You know that y = 2x - 3, so put y = 0 into this equation. 0 = 2x - 3 -> 3 = 2x -> x = 1.5 So the line meets the horizontal axis when x = 1.5 For (b) the equation meets the vertical axis when x = 0 So again put that into y = 2x - 3 So y = 2*0 - 3 -> y = -3 So the line meets the vertical axis when y = -3. Draw a line through these two points (1.5,0) and (0,-3) and there you have your graph.
the origin and it has the coordinates of (0,0)
The x-axis comes first. because x comes before y.
The vertical axis is the y-axis. The horizontal axis is the x-axis.
In the coordinate plane, the x-axis is horizontal, and the y-axis is vertical.
The x axis is horizontal and the y axis is vertical.
The convention for an x-y graph is as follows: y | | |_____ x where the x-axis is horizontal and the y-axis is vertical.
On graph paper. The horizontal line is the x-axis. The vertical line is the y-axis. Where the two line intersect is deemed to be the origin, and given the co-ordinates , in (x,y) form , of (0,0).
