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.
What is a linear graph?
A linear graph is a model of a straight line on the X and Y axis. It represents the equation y=mx+b. A liner graph has a slope. A liner graph cannot be equaled to 0.
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.
Hiw to grapgh a linear equation?
To graph a linear equation, one must first simplify it into the slope-intercept form, y=mx+b, where m is equal to the slope of the line. Next, one must find the x and y coordinates. By making x equal to zero the equation can be simplified into y=b, giving the coordinate (0,b). Plot this point on your graph. By making y equal to zero, the equation becomes x=[(-b)/m], giving the coordinate ([(-b)/m], 0). Plot this point on your graph. Once you have both coordinates marked, simply connect these two points with a line.
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.

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.

Is 2x plus 3 plus 0 a linear equation?
for something to be an equation it has to be equal to something.2x+3=0 would be a linear equation (with x=-1.5) 2x+3+0 is just a series of terms.

Why can't a coefficient of x and y in standard form of a linear equation cannot both be zero?
Standard form of a linear equation is represented as Ax + By = C If A and B are the coefficients of the x and y and they are both equal to zero then C would always be equal to 0 for any given x and y value. 0x + 0y = 0 Since the linear equation is an equation between two variables that gives a straight line when plotted on a graph, (0,0) is a point itself and wouldn't be able to form a line.
Y 2x plus 3 graph?
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.
If the graph of a linear equation Ax plus By equals C passes through the origin then will C equal 0?
Yes Ax + By = C As the line passes through the origin then x = 0 when y = 0. Substituting gives, 0 + 0 = C therefore C = 0.
Is 5x - 5 a linear equation?
0
Why can't an equal 0 in a quadratic equation?
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
