## How do you find the value of y?

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 – y2] / [x1 – x2]. If you know x, you can solve for y to find the y value for the slope of the line.

## What does Y mean in a equation?

Note: A function defines one variable in terms of another. The statement “y is a function of x” (denoted y = y(x)) means that y varies according to whatever value x takes on. A causal relationship is often implied (i.e. “x causes y”), but does not *necessarily* exist.

## 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 number is Y in math?

Math “Y” Terms. y-axis The vertical number line in a coordinate graph. The line in the coordinate plane, usually vertical, or in space, containing those points whose first coordinates (and third, in space) are 0. y-coordinate The second coordinate of an ordered pair or ordered triple.

## What does Y stand for in the equation y MX B?

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.

## Can the Y in Y MX B be negative?

No, the y in slope-intercept form equation cannot be negative. By definition, the slope-intercept form of a line is y = mx + b.

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

2 Answers. The the slope is 2.

What is the equation of exchange equal to? So the equation of exchange says that the total amount of money that changes hands in the economy will always equal the total money value of the goods and services that change hands in the economy. So now the equation of exchange says that total nominal expenditures […]

#### Calcium and water balanced equation

What happens when calcium reacts with water? After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide. What is the balanced equation for calcium oxide and water? CaO(s) + H2O (l) → Ca(OH)2(s) This reaction occurs […]
