On a number line x=3 is a dot and x=-2 is a dot that is measure the distance each is from zero, respectively.
On an (x,y) graph they would be vertical lines crossing the x-axis at the appropriate places.
It's an absolute measure (like a ruler), you are not comparing it, in relation to anything else. So linear.
No, y=8 is a fixed value. A linear equation would look something like y=x+8 - That would produce a straight line graph if the values of x & y were plotted against each other on a graph.
Which frequency? Frequency in Hertz can be accepted as linear frequency. What is non linear is usually the method of "presenting" it, like a non linear logarithmic scale. Also there is the matter of angular frequency defined as w = 2*π*f, where f is linear frequency (Hz or s^-1).
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
Looks like a linear equation to me, and a ridiculously easy one at that.
You mean -1 = xy , right? If we think of y against x, then it's like y = -1/x .... It's not linear. But if we consider y against 1/x , it's linear....
The statement "21000 feet of lineal foot of fencing" is incorrectly worded. At some point in time someone decided that LINEAL was a descriptive word that should be used to describe a unit of measure. Lineal refers to ancestry or heredity - so the definition of a "lineal foot" would mean someone's foot (like your grandmother) that is related to you. The correct term for measurement is actually LINEAR, i.e., one (1) linear foot equals twelve (12) inches. Linear feet and feet are the same measurement. Therefore, 1 foot equals 1 linear foot.
Sure. That would be OK.16 inches on the map would represent (16 x 1500) = 24,000 miles, roughly the earth's circumference.16 inches or a little bit bigger to represent the whole surface of the earth, cut up and flattened out ...that's reasonable.
Most functions are not like linear equations.
It's a trivial linear equation in 'x'.You can find the solution like this:-104 = 8xDivide each side by 8:-13 = x
If you would like to know what a short scale measurement is when applied to questionnaires, it is a measurement tool used by psychiatrists. It measure a person's mental capacities.
Y=A+BX; X=machine hours. Sounds like a linear regression. 3x - y = 5 x + 3y = 5
