X and y intercepts of -2x+7y=14

Question

What is the x and the y int of  5x-y=5

Answer 1

-2x+7y=14

x=0

7y=14

y=2

y=0

-2x=14

x=-7

 

5x-y=5

x=0

-y=5

y=-5

y=0

5x=5

x=1

Answer 2

-2x + 7y = 14

7y = -2x + 14

y = -2x/7 + 2

 

y-intercept at x = 0, (0, 2)

 

x-intercept at y = 0

0 = -2x/7 + 2

2x/7 = 2

2x = 14

x = 7    

 

x-intercept at (7, 0)
