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).
Only if the two functions really represent the same function.
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.
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.
YES...A direct variation is a linear relationship in which y-intercept is always 0.
Any function of the form:f(x) = mx + b where "m" is the slope, and "b" is the y-intercept.
it is impossible for a linear function to not have a y-intercept

Yes
X = 3 A vertical line not having a 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.
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.
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.
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.
looking they can't of got far
y=ax+b a=slope b=y intercept
