No; if the slope is zero and it is above or below y=0 it will not have an x intercept.

How do you graph a linear equation slope intercept?

You can graph a linear equation slope intercept by solving the equation and plugging in the numbers : y=mx+b


What is the y-intercept of a linear equation?

The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.


How can you find the y intercept of the graph of a linear equation?

At a y-intercept, the graph touches the y-axis, meaning the value of x is 0. So, in any linear equation, simply set x equal to 0 and solve for y. In the slope-intercept form of a linear equation (y = mx + b), the y-intercept value is represented by the variable b.


How do you find the x intercept on a linear equation?

At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.


Do all linear equations need to be proportional?

No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.


What does the graph of the equation 2x-3y equals 6 look like?

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph


What are 3 different methods that can graph a linear equation?

You could put the equation in slope-intercept form or in parent linear function or even make a table of values.


How do you find the y-intercept of a linear equation?

First write it in the "slope-intercept" form : y = mx + c Then the y-intercept is (0, c)


What is the smallest number of intercepts possible for a graph of a linear equation in 2 variables?

The graph must have at least one intercept.


Which of the following is the slope-intercept form of the equation?

The slope-intercept form of the equation is y = mx + b, where m represents the slope and b represents the y-intercept. It is used to graph linear equations easily.


How do you find the y-intercept of a linear relationship from a graph?

To find the y-intercept from a graph - look at where the graph of the line intersects the y-axis. The point at where the graph of the line crosses the y-axis will be the y-intercept with the coordinates of (0,y) The point at which the line cuts the y – axis is called as y – intercept.You can locate the point by seeing the graph.Note:If you are given a linear equation say ax + by + c = 0Now if we plug x = 0 in the given equation we will get the y – intercept.y = -c/bIf the given equation is of the form y = mx + bb is the y – intercept of the line.
