Linear Equation And Their Graphs Math
In this unit we learn about linear equations and how we can use their graphs to solve problems.
Linear equation and their graphs math. Example 1 graphing a linear relation using intercepts. Plotting 0 3 and 2 0 gives the graph in figure 3 7. Using algebra we can solve the linear equation 1 2x 1 3 as follows. Our mission is to provide a free world class education to anyone anywhere.
Geometrically this is the x value of the intersection of the two graphs f x 1 2x 1 and g x 3. Let s see how our math solver generates graphs of this and similar problems. Graph 3x 2y 6. 3 0 2y 6 2y 6 y 3 for the x intercept let y 0 getting 3x 2 0 6 3x 6 x 2.
Intercepts of linear equations functions slope of linear equations functions slope intercept point slope standard forms graphing linear equations functions writing linear equations functions interpreting linear equations functions linear equations functions word problems. Khan academy is a 501 c 3 nonprofit organization. The y intercept is found by letting x 0. Finding the slope of a line from 2 points.
1 2x 1 3 1 2x 2 2 1 2x 2 2 x 4 the solution to this equation is x 4.
