Why is product of slopes of x axis and y axis not equal to one?
We know that the slope of a line is (Changes in y)/(Changes in x). Does the y-axes has changes in y? No. This means that y-axis does not have a slope. The same thing is for x-axis.
Which three features describe a line graph?
.Has an x-axis and a y-axisShows how a variable changes in relation to another variableShows the independent variable on the x-axis
What are geometric transformation?
shown on graphs . 3 types : translation , rotaation , reflection x , y - -x ,y = reflection over y axis x,y- y,-x = reflection over x- axis translation= x,y - x+ or - horizontal change , y+ or - vertical change Perfect reflection= x,y - y,-x 180 degree rotation = x,y - -x , -y 90 degree clockwise rotation=x,y - y , -x 90 degree counter clockwise rotation = x,y - -y,x when graphing transformations , label the new image points as primes . When theres more then one prime , up the amount. Ex: A(1,0) becomes A'(A prime) (-1,0) hope this helps!
What is the x and y intercept of x-3 y equals 9?
Set x=0, solve for y, which is the y intercept: 0 - 3y = 9 --> y = -3. Set y=0 and solve for x = 9 for x-intercept.
What is x-intercept and y-intercept?
The graphical concept of x- and y-intercepts is pretty simple. The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. The problems start when we try to deal with intercepts algebraically.To clarify the algebraic part, think again about the axes. When you were first introduced to the Cartesian plane, you were shown the regular number line from elementary school (the x-axis), and then shown how you could draw a perpendicular number line (the y-axis) through the zero point on the first number line. Take a closer look, and you'll see that the y-axis is also the line "x = 0". In the same way, the x-axis is also the line "y = 0".Then, algebraically,an x-intercept is a point on the graph where y is zero, anda y-intercept is a point on the graph where x is zero.More specifically,an x-intercept is a point in the equation where the y-value is zero, anda y-intercept is a point in the equation where the x-value is zero.
WHEN are the words independent and dependent used to describe related variables?
If there are two variables X and Y such that changes in the value of X cause changes in the value of Y but changes in Y do not cause changes in X, then X is the independent variable and Y is the dependent variable.However, if changes in the value of X cause changes in the value of Y and changes in Y cause changes in X, then both X and Y are dependent variables.
What is the gradient of y equals 3x plus c?
Three, each time that x changes 1 y changes 3. C is where the start is.
What are some chemical and physical changes starting with w x y and z?

What is the meaning of the term elastic and inelastic?
x is elastic to y: when y changes, x tends to change a lot with it. x is inelastic to y: when y changes, x does not change much with it.
What happens to the value of y when the value of x changes in y equals 4x?
y = 100 - 4x ( a ) Find the value of y when x = 20.
Why is product of slopes of x axis and y axis not equal to one?
We know that the slope of a line is (Changes in y)/(Changes in x). Does the y-axes has changes in y? No. This means that y-axis does not have a slope. The same thing is for x-axis.
What pictures start with an x or y?
Pictures of a xylophone start with x. Pictures of a yacht start with y.
Do coordinates start with the y axis or x axis?
the start on the x axis or the horizontal line! (x,y)
What does the slope tell you about changes in x and y?
slope is change in y over change in x
Coefficient of regration x on y?
Conventionally, the dependent variable is denoted by y, the independent variable(s) by x; and the regression is of y on x. The coefficient of regression of x on y is a measure of the degree to which variations in y are reflected by variations in x. This does not mean that changes in y cause changes in x since both could be affected by something else entirely.

Is y equals x - 4 a linear function?
Yes, since y changes proportionally with x.
