∙ 12y ago
you plug in the value of y and solve for x by algebra
For example, standard form is y = mx + b
Say y = 3x + 4 and you are given y = 7
then
7 = 3x + 4
3 = 3x
1 = x
x = 1

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 use a graph to find the output value of a linear function for a given input value?
You how to remember input and output is like a machine do the rest.
An equation for a line in the xy-plane allows you to find the value of y given x?
True.
What is the equation for finding the nth term of a nonlinear sequence?
There is no set equation for finding the nth term of a non- linear sequence. You have to go through a procedure to find the equation suitable for your given sequence. You would have to post the equation itself or re phrase your question for the answer.
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 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 can you find another linear equation equivalent to the one given?
You can multiply both sides of an equation by a non-zero constant.
How do you find the y-intercept of a linear relationship from an equation?
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 = 62y = 6y = 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 an equation of a linear function?

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 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.
Find the linear equation in slope-intercept form given the following information m -1 and b 5?
y=-x+5
How do you use a graph to find the output value of a linear function for a given input value?
You how to remember input and output is like a machine do the rest.
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.
An equation for a line in the xy-plane allows you to find the value of y given x?
True.
What is an linear equation?
It is a certain type of equation used in Algebra. It uses letters to replace numbers and the aim of cracking the equation is to find the value of the letter. Such as: 4b+2=26 ....you would need to find the value of 'b'. -2( 4b= 24 )-2 ( b=6 )divided by 4 I've just solved the equation.
What are linear equation used for?
Linear equations are used to find the value of missing numbers. They are also used to find the relation among the missing numbers. For example= x+3=4 x=4-3 x=1
