Does a line graph show the relationship between three variables?
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
How do you multiply standard deviations?
Multiply them as you would any two numbers. However, you should note that the standard deviation of a product of two variables is not the product of their standard deviations. That is, SD(XY) ≠SD(X)*SD(Y)
In the xy-plane the y-axis contains all ordered pairs such that?
the x-coordinate is 0, apex :)
What is the probability that a male will inherit an X-linkedrecessive allele from his father?
There is no possibility that a male will inherit and X-linked recessive allele from his father because for a male child the father only contributes the Y chromosome to his son (of the XY pair he has). If the fater's X chromosome has a recessive allele then it is 100% certain that he will pas this on to all his daughters.
Probability of having a boy or a girl?
The probability of having a boy or a girl is always 50/50 because the female has to X sex chromosomes and the male has one X and one Y sex chromosome. If you do a Punnet Square, there will be two squares with XY and two squares with XX. With four squares in all that makes a 50/50 chance.
If you are given the graph of a line in an xy-plane and its corresponding equation you can be sure that the coordinates of every point on that line will satisfy the equation?
Yes, I'm confident of that.

What does the math term graph mean?
it means that you are plotting the points on a graph, or XY coordinate plane
Is a coordinate graph the same as a coordinate plane?
no, coordinate graph is a graph made on a coordinate plane i.e xy-plane
Do linear equations form a line?
Yes, the graph of a linear equation can be a line. There are special cases, sometimes trivial ones like y=y or x=x which are linear equations, but the graph is the entire xy plane. The point being, linear equations most often from a line, but there are cases where they do not.
What is the slope of the line with equation x equals 4?
x = 4 is a straight line that is vertical when plotted on the xy graph, where y is the vertical axis and x is the horizontal axis. A vertical line has an infinite slope; the slope is infinity
What is an example for xy intercept?
the example is a graph with an x and y axis
How is line m is the perpendicular bisector of XY. If line m intersects XY at point Z statements must be true?
The perpendicular bisector of the line XY will meet it at its midpoint at right angles.
Is line xy the same as yx?
Yes, xy is the same as yx, but should always be written as xy.
Why the line x 4 is a vertical line?
When x = 4 is graphed in an xy plane, it is easy to see why a vertical line is formed. At every value of y, x = 4. Plot enough points like this on your graph and you will soon form a vertical line.
When creating a graph indicate where each variable should be placed?
on the xy axes.
What is a quadrant on a graph?
On an XY graph, the X axis and Y axis create four separate areas. Each one is a quadrant.
