All you need to know is the slope rate and the y-intercept. Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5.

Remember your rules for dividing integers? Plot your second point.

That is equal to negative How do we write an equation for a real world problem in slope intercept form? So what is our change in y? In the previous lesson, Calculating Slopeyou learned how to calculate the slope of a line. So that is my x axis. So the line will looks something like that.

So negative 1 coma, 1, 2, 3, 4 ,5 6. Negative Slopes are Tricky! Line will draw a rough approximation. Each linear equation describes a straight line. In our problem, that would be Remember these tips about graphing slope because as you start to graph equations and you will be able to check your work to make sure that your graph is correct!

Use the slope intercept formula to find the slope: Is your graph rising from left to right? Your unknowns are the slope m and the y-intercept b. You need to follow the procedure outlined below. And we go down all the way to y is equal to negative 4 So this is rigth here, that is our change in y You can look at the graph and say, oh, if I start at 6 and I go to negative 4 I went down And this is just 13 over 3.

This is the so-called slope intercept form, because it gives you two important informations:The slope intercept form calculator will find the slope of the line passing through the two given points, its y-intercept and slope-intercept form of.

The vertical line shown in this graph will cross the x-axis at the number given in the equation. For this equation, the x-intercept is. Notice this line will never cross the y-axis.

A vertical line (other than x = 0) will not have a y-intercept. The line x = 0 is another special case since x = 0 is the equation of the y-axis. Now that you have these tools to find the intercepts. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

If you know two points that a line passes through, this page will show you how to find the equation of the line.

This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.).

I like slope-intercept form the best. Slope-intercept equation from slope & point. Slope-intercept equation from two points. Practice: Slope-intercept from two points. Slope-intercept form problems. Slope-intercept form review. Next tutorial.

Point-slope form. 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.
