Slope-intercept form - Algebra I - Khan Academyand season episode can u get pregnant 4 days after your period ends
Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept. In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually crosses the y-axis in this particular point you can calculate b by solving the equation for b and then substituting x and y with one of your two points. We can use the example above to illustrate this. We've got the two points -3, 3 and 3,
Answer To find the slope and y-intercept of this equation, we need to understand the Slope-Intercept Form of an equation of a line.

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. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y. If you don't know the slope, calculate it by dividing the rise of the line by the run. If you want to find the y-intercept if you only know 2 points along the line, keep reading the article!

Find Slope and y-Intercept from Equation
The slope intercept form is a way to describe the equation of a straight line a linear function., In the previous lesson, you learned how to graph points on the coordinate plane.

Linear equations come in three basic forms: point-slope, standard and slope-intercept. Although the different forms are equivalent, providing the same results, the slope-intercept form quickly gives you valuable information about the line it produces. Mathematicians call y the dependent variable because its value depends on what happens on the other side of the equation. The x is the independent variable because the rest of the equation depends on it. The constant A determines the slope of the line and B is the value of the y -intercept.
