Download 4.2 Graph Linear Equations The equation 2x + 5y = 8 is an example

4.2 Graph Linear Equations The equation 2x + 5y = 8 is an example of an equation in __________________. It is also a _____________________ because the variable x has a power (exponent) of one as the highest power of x. A solution of an equation in two variables is an ordered pair _________ that produces a true statement when the x and y values are substituted in the equation. Example 1 Tell whether the given point is a solution to the given equation. Is the given equation linear or not? a) (‐2, 3) for the equation –x + 2y = 8 b) (‐4, 1) for the equation x2 – 4y = 16 Most times we want the _________________ on one side of the equation. Example 2 Solve each equation for y. a) y – 2x = 5 b) 3x + 2y = 8 We can graph __________________________ by making a table of values an plotting the points on the coordinate plane. Hint: Be sure to choose convenient values of x that include negative values, zero, and positive values. Example 2 Graph the equation 2x + y = 2. X y Example 3 Graph the equation ‐2x + y = 3. Example 4 Graph the equation y = ‐3. Example 5 Graph the equation x = 2. Homework: 4.2 Worksheet #1‐15
