Transcription. 1 2.3 Graphing - Slope-Intercept Form Objective: Give the equation of a line with a known slope and y-intercept.GRAPHING LINEAR EQUATIONS IN TWO VARIABLES The graphs of linear equations in two variables are straight lines. 3) Use the statistical feature in excel in order to evaluate slopes, y- intercepts, and the equations of straight line graphs. The purpose of this video is to demonstrate how to use Microsoft excel in the following: 1) Plot graphs out of data tables 2) organize graphs by titling The line we need to graph is the hypotenuse of the right triangle. Note that the slope for this equation and graph is. , or "two over three".This always happens the y-intercept (that is, the place where the line crosses the y-axis) for a straight line with equation "y mx b" is always going to be at y b. problem. Constant Rate of Change/Slope. In a Table. Relationships that have straight-lined graphs are called linear relationships.You can use the slope-intercept form of an equation to graph the equation. Linear equations graph as a straight line using the slope intercept form of y mx b, where "m" is the slope and "b" is the y-intercept, or point where the line crosses the y-axis. The y- intercept can be used to find additional points for the line. Draw a straight line through them.B. To graph an equation using the slope and y-intercept: 1. Plot the y- intercept, (0,b). 2. Use the slope to obtain other points. In this tutorial we will be looking at graphing lines. There are several ways that you can approach graphing a line. We will be looking specifically at using the y-intercept and slope to help us get our straight line. Since a vertical line goes straight up and down, its slope is undefined.Problem 2. Look at the picture of the graph below. Find the slope of this line, its y-intercept, then express the equation of this line in slope intercept form. Slope and y-intercept from an equation: Page 8. From there on, use the slope to graph the line. Show your work and explain the method used toDemonstrates, step-by-step and with illustrations, how to use slope and the y- intercept to graph straight lines. The slope-intercept is the most popularform of a straight line.One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.

Graphing Lines Using Intercepts. Given the graph of a straight line, there are several ways to find its equation.Demonstrates, step-by-step and with illustrations, how to use slope and the y- intercept to graph straight lines. The equation of the straight line graph in slope-intercept form is y mx c. The following activity allows you to explore the properties of a straight line graph.the effects of a positive and negative value of the y-intercept, c. Every straight line can be represented by an equation: y mx b. The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. Slope and y-intercept. Graphing linear equations. However, slope intercept equation is said to be unique and has two parameters slope and y - intercept.As the given equation represents the equation of a straight line we wish to graph y 2x 3 by determining two points. Drag point A or point B, your could get result of linear equation in the form y mx b. Then you can get: A vertical line (What is m? The graph also crosses the y-axis at the point (0, 2). This point is called the y- intercept. To find the x-intercept, let y 0. (Any point on the x-axis has y-coordinate 0). To find the slope of a straight line. Graphing and solving system of linear inequalities and equat. by a straight line. y. x 0 2. -3. If you need to see the grid lines, click on the above graph, then View-> Grid lines 4.) Graph using slope and y-intercept method Describe a straight-line graph in terms of its slope and y-intercept.Determine average velocity or instantaneous velocity from a graph of position vs. time.Figure 2 is just such a straight-line graph. It shows a graph of displacement versus time for a
