1 WRITING LINEAR EQUATIONS FINDING THE X-INTERCEPT AND Y- INTERCEPT

2 Standard form of an equation of a line Examples 2x + 3y = 9 ⅖ x - 5y = 10 x + 9y = 0 Counter-Examples 3y + 5x = 9 5x = 9y + 2 y = 3x + 1

3

4 Your Turn! Find the x-intercept and y-intercept of: 2x + 3y = 12

5 PRACTICE Graph the following lines using the x-intercept and y-intercept 1.) -3x + y = 62.) 5x - 3y = -6 X-intercept: -2 Y-intercept: 6 X-intercept: -6/5 Y-intercept: 2

6 Practice Find the x-intercept and y-intercept of: 1. x + y = 3 2. x + 3y = -3 3. -2x + 3y = 6 4. 5x - 4y = -20 Graph the following equations by solving for the x- intercept and y-intercept of: 1. 3x + y = 3 2. -3x + 5y = 15 3. 2x + y = 3 4. 8x - 3y = 24
