Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist. Over the years we have used advertising to support the site so it can remain free for everyone.

Students graph proportional relationships and understand the unit rate informally as a measure of the steepness of the related line, called the slope.

This type of linear equation was shown in Tutorial Connect with algebra tutors and math tutors nearby. Students use their understanding of ratios and proportionality to solve a wide variety of percent problems, including those involving discounts, interest, taxes, tips, and percent increase or decrease.

Although you have the slope, you need the y-intercept. To understand why, go to this interactive tutorial.

Let's first see what information is given to us in the problem. Solve real-life and mathematical problems using numerical and algebraic expressions and equations. Slope intercept form of a Line: As shown above, whenever you have a vertical line your slope is undefined.

The answer is the slope is 2 and the y-intercept is If you are given slope and a point, then it becomes a little trickier to write an equation. For now, you can think of the slope as the direction of the line.

Check out the entire list of lessons Here are a few of the ways you can learn here Now we know the slope m is -2 because that was given to us. Students work with three-dimensional figures, relating them to two-dimensional figures by examining cross-sections. If you said vertical, you are correct.

We know the slope and a point x,y. They solve real-world and mathematical problems involving area, surface area, and volume of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes and right prisms.

Notice that in the chart, the 2 grey sections slope and y-intercept are the two numbers that we need in order to write our equation. Any straight line in a rectangular system has an equation of the form given above.

This example is written in function notation, but is still linear.

In our problem, that would have to be 2. We also now know the y-intercept bwhich is 9 because we just solved for b. Once you have m slope and b y-interceptyou can write an equation in slope intercept form.Recall that the slope (m) is the "steepness" of the line and b is the intercept - the point where the line crosses the y-axis.

In the figure above, adjust both m and b. If you need help in preparing for the math part of the GRE general test, you have come to the right place. Note that you do not have to be a student at WTAMU to use this study session.

Edit Article How to Find the Y Intercept. In this Article: Article Summary Finding the Y-Intercept from the Slope and Point Using Two Points Using an Equation Community Q&A The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis.

Ask Math Questions you want answered Share your favorite Solution to a math problem Share a Story about your experiences with Math which could inspire or help others. There are two ways to approach this problem.

First, you can look at this as a horizontal line, any horizontal line has the standard form equation of y = b where b is the y palmolive2day.com the slope is 0, and only horizontal lines have a slope of zero, all points on this line including the y-intercept must have the same y value.

This y-value is 5, which we can get from the fact that the line. This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.). I like slope-intercept form .
