Warm-up Date 01/26/09 Sec 6-2 Slope-Intercept Form Find the slope and y-intercept of each equation. Write an equation of a line with the given slope and y-intercept.
Date 01/26/09 Sec 6-4 Standard Form
Goal: • To graph equations using intercepts • To write equations in standard form
…And Why To use an equation to model a real-world situation that involves exercise, as in Example 5
Key Words: standard form of a linear equation: is Ax + By = C, where A, B, and C are real #’s and A and B are not both zero. x-intercept: Where the graph intersects the x-axis.
Find the x- and y-intercepts of each equation. To find the x-intercept set y = 0 and solve for x. To find the y-intercept set x = 0 and solve for y.
Graph each equation using x- and y-intercepts. To find the x-intercept set y = 0 and solve for x. To find the y-intercept set x = 0 and solve for y.
Graph each equation. No matter what x is y = 3. No matter what y is x = -4.
