#### Solve the equation for y

## How do you get y by itself in an equation?

Students learn to convert a linear equation to slope-intercept, or y = mx + b form, by getting y by itself on the left side of the equation. For example, to convert the equation x – 3y = -12 to y = mx + b form, the first step is to subtract x from both sides to get –3y = -x – 12.

## What is the formula for a linear equation?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

## What is X Y math?

An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. Every point on the plane is represented by two numbers, known as its coordinates.

## What is the slope of y equals 2x 1?

2 Answers. The the slope is 2.

## What is the slope of y =- 12?

zero

## What does solving for Y mean?

Solving for y means that we have to get y by itself. Therefore, we have to move everything else to the other side.

## What is the golden rule for solving equations?

Do unto one side of the equation, what you do to the other! When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.

## What are the 3 methods for solving systems of equations?

There are three ways to solve systems of linear equations in two variables: graphing. substitution method. elimination method.

## What are the 4 steps to solving an equation?

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.

## What are the 3 types of equations?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

## What is the formula for Y intercept?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
