What does isolate Y mean?
Isolating a variable means rearranging an algebraic equation so that a different variable is on its own. The goal is to choose a sequence of operations that will leave the variable of interest on one side and put all other terms on the other side of the equal sign.
How do you isolate y in slope intercept form?
Solution: Remember, all you have to do to transform an equation into slope-intercept form is to solve it for y. To isolate the y, subtract x from both sides of the equation and then divide everything by the coefficient of – 4: -4y = -x + 12.

What is Y as a number?
y is a variable just like x is a variable. So what’s a variable, right? It’s a symbol we use when we don’t know how many we have of something or when the number of them can change. y + 5 means we add 5 to whatever we decide y stands for. It could be any number, so we’re just holding its place with the variable.
What is Y in algebra?
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”
How do you find the y-intercept without graphing?
When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. To find y-intercept: set x = 0 and solve for y. The point will be (0, y).

What is the y-intercept formula?
y-Intercept in Slope-Intercept Form
The equation of the line in the slope-intercept form is, y=mx+b. By the definition of the slope-intercept form itself, b is the y-intercept of the line.
How do you solve for slope?
- The difference between y coordinates Δy is.
- The difference between x coordinates Δx is.
- Divide Δy by Δx to find slope m.
How do you make a variable by itself?
The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.

How do you get rid of a variable?
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
How do you write y MX B on a graph?
We can write the slope-intercept equation from a graph. The point where the graph crosses the y-axis is our b-value. The slope is our m-value. Plug these into y=mx+b.
