WRITING LINEAR EQUATIONS

FINDING THE X-INTERCEPT AND Y-INTERCEPT

Page 2: WRITING LINEAR EQUATIONS FINDING THE X-INTERCEPT AND Y- INTERCEPT

Standard form of an equation of a

line

Examples

2x + 3y = 9

⅖x - 5y = 10

x + 9y = 0

Counter-Examples3y + 5x = 9

5x = 9y + 2

y = 3x + 1

Page 4: WRITING LINEAR EQUATIONS FINDING THE X-INTERCEPT AND Y- INTERCEPT

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

= 12

Page 5: WRITING LINEAR EQUATIONS FINDING THE X-INTERCEPT AND Y- INTERCEPT

PRACTICEGraph the following lines using the x-

intercept and y-intercept

1.) -3x + y = 6 2.) 5x - 3y = -6X-intercept: -2Y-intercept: 6

X-intercept: -6/5Y-intercept: 2

Page 6: WRITING LINEAR EQUATIONS FINDING THE X-INTERCEPT AND Y- INTERCEPT

PracticeFind the x-intercept and y-intercept of:1. x + y = 3

2. x + 3y = -33. -2x + 3y = 64. 5x - 4y = -20Graph the following equations by solving for the

x-intercept and y-intercept of:1. 3x + y = 32. -3x + 5y = 153. 2x + y = 34. 8x - 3y = 24
