This is going to be a lot like what we just did at the end of the last section. So far, I've shown you how to find the slope from the graph and when you have two points

In the previous lesson, you learned how to graph points on the coordinate plane. We can connect two points with a straight line. To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations " linear " because the graph of these equations is a straight line. There are two important things that can help you graph an equation, slope and y-intercept. Slope We're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes.



Writing linear equations using the slope-intercept form

The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y.

Slope Intercept Form Calculator

The slope intercept form calculator will teach you how to find the equation of a line from any two points that this line passes through. It will help you to find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas. Read on to learn what is the slope intercept form of a linear equation, how to find the equation of a line and the importance of the slope intercept form equation in real life. Any line on a flat plane can be described mathematically as a relationship between the vertical y-axis and horizontal x-axis positions of each of the points that contribute to the line. The specific form of [something with x] will determine what kind of line we have. In this slope intercept calculator, we will focus only on the straight line , but those interested in knowing more about the parabolic function should not worry. We have two special calculators dedicated to such an equation, namely the parabola calculator and the quadratic formula calculator.

The slope intercept form is a way to describe the equation of a straight line a linear function. Scroll to the bottom of this explanation to see some examples of equations in slope intercept form. In slope intercept equations y and x will always appear as y and x , because they are variables that describe the position of specific points on the graph. For more information about slope, see these explanations. Slope can be positive or negative, so keep that in mind when you read slope intercept equations.

Slope-intercept form - Algebra I - Khan Academy

Every straight line can be represented by an equation: y = mx + b. The coordinates of every point on the line will solve the equation if you substitute them in the.

Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y -intercept can easily be identified or read off from this form. So our next goal is to somehow figure out what the value of b first. Again, the value of y -intercept b is not directly provided to us. But we can utilize the given slope and a point to find it. Substitute the known values into the slope-intercept formula, and then solve for the unknown value of b. The procedure for solving this problem is very similar to examples 3, 4 and 5.
