How do you find the x-coordinate of a point on a line if you have another point and the slope? You'll need to use the slope formula. Watch this tutorial and see how to find this missing coordinate!
Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!
Ordered pairs are a crucial part of graphing, but you need to know how to identify the coordinates in an ordered pair if you're going to plot it on a coordinate plane. In this tutorial, you'll see how to identify the x-coordinate in an ordered pair!
Subtracting a negative from a positive? Just remember: subtracting a negative is the same as adding a positive. See how it works in this tutorial!
Solving an equation for a variable? Perform the order of operations in reverse! Check it out in this tutorial.
When you're dealing with linear equations, you may be asked to find the slope of a line. That's when knowing the slope formula really comes in handy! Learn the formula to find the slope of a line by watching this tutorial.
You can't learn about linear equations without learning about slope. The slope of a line is the steepness of the line. There are many ways to think about slope. Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line. Check out this tutorial to learn about slope!
Want some practice finding the y-intercept of a line? In this tutorial, you're given the slope of a line and a point on that line and asked to find the y-intercept. Watch this tutorial and see how the equation for the slope-intercept form of a line is used to figure out the answer!
Calculating the slope of a line from two given points? Use the slope formula! This tutorial will show you how!
Word problems are a great way to see math in action! This tutorial shows you how to solve a word problem involving rise and run by using the slope formula.
