How can you use graphs to determine the x intercept of the graph of linear function?

Extend the line until it hits the x axis and that is the x intercept. If the line is not parallel to the x axis, then extending it one way will reach the x axis, the other way will not. If the line is parallel to the x axis it will never meet it (or, if you like, it will meet it at plus or minus infinity, which is another way of saying never).

Is it possible for 2 linear functions whose graphs are parallel lines to have the same y-intercept?
Only if the two functions really represent the same function.
What is important about the y intercept?
The y-intercept is where a graph cuts the y-axis. (When the x coordinate = 0) All linear graphs can be expressed in the form y = mc + c where m is the gradient and c is the y - intercept.
What is the difference between linear and non linear graphs?
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.
Is the direct variation of two variables always a linear function?
YES...A direct variation is a linear relationship in which y-intercept is always 0.
What is A Function That Forms A Line When Graphing?
Any function of the form:f(x) = mx + b where "m" is the slope, and "b" is the y-intercept.
A linear function does not have a y-intercept?
it is impossible for a linear function to not have a y-intercept

IS it possible for a graph of a linear function to have no intercept?
Yes
Can a linear function does not have a y-intercept?
X = 3 A vertical line not having a Y intercept.
What is important about the y intercept?
The y-intercept is where a graph cuts the y-axis. (When the x coordinate = 0) All linear graphs can be expressed in the form y = mc + c where m is the gradient and c is the y - intercept.
What is the difination of linear function?
A linear function is any function that graphs to a straight line. What this means mathematically is that the function has either one or two variables with no exponents or powers. If the function has more variables, the variables must be constants or known variables for the function to remain a linear function.
Can a linear function not have a y-intercept?
No, it would have to be parallel to the y-axis, making the slope undefined and having only a single x-value. Not a linear function.
What is the difference between linear and non linear graphs?
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.
How do you find the slope and y intercept of a linear function by algebra?
looking they can't of got far
How do you find the rule for a linear function?
y=ax+b a=slope b=y intercept
Is the direct variation of two variables always a linear function?
