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 the x intercept and the y intercept of x-9y equals 18?
x - 9y = 18At the x-intercept, y=0 :x = 18At the y-intercept, x=0 :-9y = 18-y = 2y = -2
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.
Half life 2 cheats?

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