# Write an equation in slope and y-intercept form

What is the slope intercept form Linear equations, or straight line equations, can be recognized by having no terms with exponents on them. I substituted the value for the slope -2 for m and the value for the y-intercept 5 for b. If you are given slope and the y-intercept, then you have it made.

We also now know the y-intercept bwhich is 9 because we just solved for b. Now enter a right parenthesis and press Crtl-Shft-Enter. The graph would look like this: So this would be a negative over a positive, it would give you a negative number.

The following are examples of a rate: Let's think about what we know in this problem. Notice that in the chart, the 2 grey sections slope and y-intercept are the two numbers that we need in order to write our equation. The equation is y-- let me do it in a new color-- y is equal to negative 2x plus b plus Slope intercept formula derivation How to find the slope intercept form of a linear equation, then?

So they tell us that f of 1. This is just a fancy way of saying that both of these two points are on the line, nothing unusual. If our run is positive, our rise here is negative. Two proofs are given, one of which does not use calculus. So you get 0 is equal to plus b. This is equal to 6 minus 0 is 6. Locate another point that lies on the line. Because if you move in the positive x direction, we have to go down. The best fit line is called the regression line. What is the change in y?

So change in x is 1. Since you are so awesome at solving equations, I'm sure this wasn't too painful. This will define equation in the example above, part a. Example Find the x and y intercepts of the graph of the equations given below. Now we know the slope m is -2 because that was given to us.

Put all these values together to construct the slope intercept form of a linear equation: You have enough information to find the y-intercept, but it requires a few more steps. The properties of the graph such as slope and x and y intercepts are also explored.Recall that the slope (m) is the "steepness" of the line and b is the intercept - the point where the line crosses the y-axis.

In the figure above, adjust both m and b. The slope intercept form calculator tells you how to find the equation of a line for any given two points that this line passes through.

It will help you find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas. Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.

Slope-Intercept Method: Probably the most common way to graph a line is put the equation in the infamous $$\boldsymbol{y=mx+b}$$ form: graph the $$y$$-intercept point first, and then use the slope to go back and forth, and up and down from that first point.

For our equation $$\displaystyle y=-\frac{2}{3}x-2$$, the slope $$\displaystyle m=-\frac{2}{3}$$, and the $$y$$-intercept $$b$$ = –2. The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.

Adjust the sliders above to vary the values of a and b, and note the effects they have on the graph. Another form. Learn why the Common Core is important for your child. What parents should know; Myths vs. facts.
