This book, 8-B, covers the topic of graphing linear equations. The focus is on the concept of slope. In chapter 6, our focus is on square roots, cube roots, the concept of irrational numbers, and the Pythagorean Theorem and its applications. Next, in chapter 7, students solve systems of linear equations, using both graphing and algebraic ...

The equation of a straight line is ymx c=+, where m = gradient and c = intercept (where the line crosses the y-axis). Example 1 Draw the graph with equation yx=+23. Solution First, find the coordinates of some points on the graph. This can be done by calculating y for a range of x values as shown in the table.

Linear equations may be written in several forms: Slope-Intercept Form: y = mx+ b In an equation of the form y = mx + b, such as y = −2x − 3, the slope is m and the y-intercept is the point (0, b). To graph equations of this form, construct a table of values (Method 1) or use the slope and y-intercept (Method 3) (see Examples 1 and 6).

Graphing Vertical and Horizontal Lines i. The preceding methods will not work for equations in the form x = a or y = b. ii. Vertical Lines 1. Equation: x = a 2. The graph is a line parallel to the y-axis and passes through the x-intercept (a, 0). 3. All the x-coordinates on the line are a. 4. The slope of a vertical line is undefined. Example 7 ...

4.1 Graphing Linear Equations and Inequalities 192 Graph =5 −3 by plotting points. 4.1.2 Graphing Using Intercepts The next method discussed is the intercept method.Recall that the x-intercept of the graph of an equation is the point(s) where the graph intersects the x-axis.Similarly, the y-intercept of the graph of an equation is the point(s) where the graph intersects the y-axis.

II. QUADRATIC EQUATIONS Only linear equations have graphs that result in lines. The graphs of all nonlinear equations will be “curves”. An equation in the form y =ax2 +bx +c (a ≠0), is referred to as “Quadratic” and its graph is a parabola. Here are examples of the graphs of two quadratic equations along with the tables used to find ...

Now, assign values of x and find the corresponding y’s. Graphing each ordered pair, our graph looks like this: If we take the same problem and realize the graph crosses the x-axis when y = 0, and crosses the y-axis when x = 0, watch what happens. EXAMPLE: 3x – 4y = 12 When x = 0, the 3x falls out of the problem, so –4y = 12 or y = –3.

Intro to Linear Equations Algebra 6.0 Linear Equations: y 2x 7 5 2 1 y x 2x 3y 12 Linear Equations generally contain two variables: x and y. In a linear equation, y is called the dependent variable and x is the independent variable. This is because y is dependent on what you plug-in for x. The domain of a linear equation is the set of all x ...

Graphing Linear Equations . Linear equations are used to form straight lines on a graph. The ability to graph a linear equation is essential to understanding and analyzing information . This handout will discuss the coordinate plane, how to plot points on the coordinate plane, and how to graph a linear equation in slope-intercept form.

equations and graphs of parallel lines and perpendicular lines. Slope-Intercept Form . One way of graphing the equation of a line is by using the slope-intercept form which identifies the slope and the y-intercept. The Slope-Intercept Form of a Linear Equation (07:15) Example #1: Identify the slope and y-intercept for the equation y = 2 3 − x ...

A line on a graph is the set of all points which satisfy some mathematical rule, which is given by the line equation. Eg For the line equation: y =2x−1 Point (0, – 1) is on the line as – 1 = 2 x (0) – 1 is true. Both sides of = come to the same value (Note that we put the - 1 in place of y and the 0 in place of x in the equation.)

Graphing a Linear Equation . Intercepts: The x-intercept is where the graph crosses the x -axis. The y-coordinate is always 0. The y-intercept is where the graph crosses the y -axis. The x-coordinate is always 0. Graphing Lines by Finding the Intercepts: Steps Example Step 1: Find y-intercept • Let x = 0 • Substitute 0 for x; solve for y.
