How can you tell if a table represents a linear relationship?
A table represents a linear relationship if the change in the dependent variable (y) is consistent with a proportional change in the independent variable (x). This can be confirmed by calculating the slope between consecutive points; if the slope remains constant, the relationship is linear. Additionally, plotting the points on a graph should yield a straight line if the relationship is indeed linear.
Can you tell how a quadratic equation can become linear equation?
You can easily tell by substituting 0 for a.
How can you tell that an equation has the same solution as the original equation?
If the two equations are linear transformations of one another they have the same solution.
How can you tell a linear function from an equation?
An equation is a statement that two things are equal. A function is a rule or process that gives you a value if you give it something in its domain (the set of things on which it is defined) as an argument. Functions on numbers that are defined by a rule can usually be expressed by an equation. A linear function is one that can be defined by a linear equation.
How can you tell by looking at an equation whether the function is linear?
You can tell if a function is linear by checking its equation for the form (y = mx + b), where (m) and (b) are constants. If the equation can be rearranged to this form, or if it involves only first-degree terms and no variables multiplied together, raised to powers other than one, or involving products of variables, it is linear. Additionally, a linear function will produce a graph that is a straight line.
How can you tell if an equation is a linear relationship?
If it is in a y=mx+b format. Also, if there is a slope and a constant in the equation.

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

If the two equations are linear transformations of one another they have the same solution.

How do you tell if an eqution is a linear equation?
An equation (note spelling) is linear if it is made up exclusively of constants and of unknowns raised to the first power (e.g., 'z', as opposed to 'z^2')

How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
How can you tell if an equation has at most one solution without solving it?
You can be certain if the equation is linear, that is, of the form ax + b = 0 where a and b are constants.
How can you tell whether a linear function can be used to model a real life relationship?
You can create a scatter plot of the two variables. This may tell you if there is a relationship and, if so, whether or not it is linear. If there seems to be a linear relationship, you can carry out a linear regression. Note that the absence of a linear relationship does not mean that there is no relationship. The coordinates of the points on a circle do not show a linear relationship: the correlation coefficient is zero but there is a perfect and simple relationship between the abscissa and the ordinate. Even if there is evidence of a linear relationship, it may be valid only within the range of observations: do not extrapolate. For example, the increase in temperature of a body is linearly related to the amount of heat energy aded. However, for a solid, there will come a stage when the additional heat will not increase the temperature but will be used to melt (or sublimate) the solid. So the linear relationship will be broken.
