The slope is negative.

This just means that your x-values (independent) are increasing (which is usually the case). Such as 0,1,2,3,4,5. While the y-values (dependent) are decreasing. such as -5,-4,-3,-2,-1,0. Since the y-values are decreasing, this must mean the slope has to be negative.

What is the independent variable of 1.49?

1.49 is a constant: there is NO variable - independent or dependent!


If xy equals 20 then y decreases as x - decreases increases or stays constant?

linear if xy = 20, then y = 20/x or y = 20(1/x) So x can be positive or negative but not zero: There are 3 cases: Case 1: if x = 20, then y is constant, y = 1. Case 2: a) if x > 0, and if x → 0+, then y → ∞ (if x decreases but not reaches zero, then y increases without end). b) if x < 0 and if x → -∞, then y → 0 (if x decreases, then y increases and approaches to zero). Case 3: a) if x > 0 and if x → ∞, then y → 0 (if x increases, y decreases and approaches to zero) b) if x < 0, and if x → 0-, then y → -∞ (if x increases but not reaches zero, then y decreases without end).


What is the variable and constant in P equals 2W 2L?

'W' and 'L' are independent variables. 'P' is the dependent variable. '2' and '2' are the constants.


What is the definition of linear equation?

A linear equation has a constant rate of change, or slope (change in y (dependent) value over change in x (independent) value), when graphed forms a straight trend line, and is in the format y=mx+b (y is dependent value, m is slope, x is independent value, and b is the y-intercept (the value of y when x=0).


What is an example of constant rate of change?

A constant rate of change is anything that increases or decreases by the same amount for every trial. Therefore an example could be driving down the highway at a speed of exactly 60 MPH. If your speed doesn't change you are driving at a constant rate. Here's another: your cell phone company charges you $0.55 for every minute you use. The rate that you are charged always stays the same so it is a constant rate of change. Anything that goes up by X number of units for every Y value every time is a constant rate of change.

Is 80 independent or dependent?

80 is neither dependent nor independent. It is a number: a variable can be dependent or independent, not a constant.

What effect does an increase in pressure have on the density of a material?

When pressure increases the volume of the material decreases. Density=mass/volume When volume decreases density increases.(Mass constant)


When the temperature is constant will the the volume of a gas decrease as the pressure decreases?

At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.


Are constant variables and dependent variables the same?

No, they are not.The constant varible is what stays the same and the dependent varible is whats effected by the change (the independent varibles).
