How do you solve for the y value?
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 is Y in algebra?
Answer: unknown number. The symbol stands for an unknown number, the symbol y stands for an unknown number and the symbol 2 stands for a known number, two. In algebra when two symbols that stand for a number are placed beside each other the operation between them is taken to be multiplication.
What is Y in math equations?
The variable which we assign the value we call the independent variable, and the other variable is the dependent variable, since it value depends on the independent variable. In our example above, x is the independent variable and y is the dependent variable.
What is Y value in math?
The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value “5” is the Y Coordinate. Also called “Ordinate”
What is y 2 on a graph?
The equation y=2 is in slope intercept form, where the slope is m=0 and the y−intercept is c=2. The equation can be graphed as the equation y=0x+2. The graph is a horizontal line where all values for y are 2.
What is the variable for Y?
A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation.
Why is Y used in math?
The letter y is commonly used as a variable in math. It is probably one of the first variables you will come across. It is usually used when referring to equations that you graph. It also is used to refer to functions.
How do you write y 2 on a graph?
The equation y=2 is in slope intercept form, where the slope is 0 and the y-intercept is 2 . The equation can be graphed as the equation y=0x+2 . The graph is a horizontal line where all values for y are 2 .
