How does a linear relationship show up in a equation?
y=mx+b
What is something with a perfect linear relationship?
A linear relationship is given by the equation y=ax+b Anything which can be modelled by this equation is a linear relationship. For example, the circumference of a circle is pi times d. This can be modelled by y=ax+b where y is the circumference, a is pi, x is the diameter and b is 0. Therefore, the circumference of a circle as the diameter changes is a perfect linear relationship.
What do you need to write a linear equation for a linear relationship?
A Y-intercept and the slope. The y-intercept is where the line crosses the Y axis.
What is proportional linear relationship in math?
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
Why was there a need to invent linear equation in two variables?
If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one.

What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
Equation for a linear relationship?
y = mx + b
Can you tell how a quadratic equation can become linear equation?
You can easily tell by substituting 0 for a.
What does the equation for a linear relationship stand for?
y=mx+b is the equation for a linear relationship. y= the dependant variable m= the slope of the line x= the independent variable b= the y-intercept
What is the difference between and linear relationship and a quadratic relationship?
a linear relationship is characterized by the form y=mx+b and a quadratic relationship is characterized by the form y=x^2+bx+c. Graphically represented, a linear equation forms a line and a quadratic will appear as a parabola.
Why would a linear trend equation based forecast be dangerous?
The relationship between the variables may not be linear.
How can the degree of the equation tell us if the equation is linear or not?
A linear equation always has a degree of one because the slope has to be constant to form a line. So, x + 7 is linear, 7 - x is linear, 4x - 3.7 is linear, but anything with x2 , etc. is not linear.

Is 4x2x a linear equation?
Difficult to tell because of problems with the browser. 4x = 2x IS a linear equation whose solution is x = 0
What is the relationship modeled by the equation y equals 8x plus 17?
A linear relationship. Added: And a function.
