The y-intercept of a linear equation is the point on the y-axis at which the line cuts.
It could be found by plugging x = 0 in the given linear equation.
For example,
Consider 3x + 2y = 6. To find the y-intercept just plug x = 0 in the equation.
3(0) + 2y = 6
2y = 6
y = 3
(0, 3) is the y-intercept of the linear equation 2x + 3y = 6.
Note:
In the same way we can find the x-intercept by plugging y = 0 in the given linear equation.

How do you find system of linear equation in two variable?
By elimination and substitution
How do you find for the zero of a linear function?
If it is a linear function, it is quite easy to solve the equation explicitly, using standard methods of equation-solving. For example, if you have "y" as a function of "x", you would have to solve the variable for "x".
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.
What symbol will you find in every linear equation?
The equals sign ( = ). In fact it defines any equation, linear or not, since an equation is a statement that a particular value or term is equal to, so the result of solving, a second set of terms and operators. Any other symbols would be particular to the equation you have derived or are trying to solve.
How can you tell from a linear equation which direction it goes without graphing the equation?
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
How do you find the y intercept of a linear relationship from an equation?
plug in a 0 for the "x" value of the equation, and solve it :D

How do you know if numbers show linear relationship?
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
How would you find a linear relationship from a verbal explanation?
No
How do you find the gradient of a Linear Equation?
If necessary, rearrange the linear equation so that it is in the slope-intercept form: y = mx + c Then the gradient of the line is m.
How do you find out if a problem is linear or exponential?
You find out if a problem is linear or exponential by looking at the degree or the highest power; if the degree or the highest power is 1 or 0, the equation is linear. But if the degree is higher than 1 or lower than 0, the equation is exponential.

How do you find the slope of a linear equation?
(y2-y1)(x2-x1) you plug in the equation to this formula and thats ur answer!
How do you find an equation from a graph?
In general, it is very difficult. Even if a graph looks like a straight line over the domain there is no guarantee that the underlying equation makes the equation non-linear as you move away from the visible domain. A typical example, from school physics, concerns Hooke's law. The extension of a length of wire under different strains follows a linear relationship. Until the strain reaches a critical level and then the relationship goes all haywire. Looking at the graph below that critical level, the equation would be a straightforward linear one. But that is true only as far as it goes.
How can you find another linear equation equivalent to the one given?
You can multiply both sides of an equation by a non-zero constant.
What is the difference between a function and linear equation?
A function is a relationship between a set of inputs and a set of outputs. The key requirement is that each allowable input relates to exactly one output value. Equations are often used to define a function. That is, the relationship is given by a rule that tells how to find the output from any given input. For example f(x)= 7x-2 says in words, given an input number, say x, multiply it by 7 and subtract 2, to get the associated output. 7x - 2 is called a linear expression because its highest power is one (and a function defined by a linear expression is called a linear function. ) A linear equation is an equation between two linear expressions. Example: 2x + 3 = 7x - 2.
What is linear programming used for?
Linear Programming is used for determining a way to find the best solution or outcome for a given mathematical model represented as a linear relationship.
