Let's explore different ways to find and visualize slopes and intercepts, and how these concepts can help us solve real-world problems. **Unit guides are here!**
Intercepts from a table (video) | Khan Academy
Since the table represents a line, there's a constant rate of change of y with respect to x. So we can find that pattern and fill in skipped values from the table to find the y-intercept.
Intro to intercepts (video) | Khan Academy
Learn what x- and y-intercepts are. The equations used in this video are y = 0.5x - 3 and 5x + 6y = 30.
Intercepts of lines review (x-intercepts and y-intercepts) (article ...
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
Graphing quadratics: vertex form | Algebra (video) | Khan Academy
Once you've graphed the vertex, move 1 unit to the left and right of the vertex to get two new "x" values to find more points to complete your graph. For each new value of "x", you use it in the …

Slope-intercept form introduction - Khan Academy
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.
Worked example: intercepts from an equation - Khan Academy
Let's find the x- and y-intercepts of the equation 2y + 1/3x = 12, where a line crosses the x-axis (the x-intercept) and the y-axis (the y-intercept) on a graph. To find the x-intercept, we make y …
Intro to linear equation standard form - Khan Academy
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find …
x-intercept of a line - Khan Academy
For a line represented by the equation y=mx+b, where m is the slope and b is the y-intercept, the x-intercept can be found by setting y to zero and solving for x.
