Which one are we looking for?

Matias is wondering how long it will take a football to hit the ground after throwing it at practice.

• x at vertex

• y at vertex

• zeros/roots/x intercept

• y-intercept

What is the x and y intercept for the following equation ?
4x - 10y = 20

• x - int = 4    
  y-int = -10

• x-int = 5
  y-int = 2

• x - int = 5
  y int = -2

• x -int = 4
  y -int = -10

In the equation 4x - 8y = -40, My x-intercept is ​ (a)   and my y-intercept is ​ (b)  

• (-10, 5)

• (10, 0)

• (0, -5)

• (5, 0)

• (-10, 0)

• (0, 5)

What is the x and y intercept for the following equation ?

4x - 10y = 20

*SHOW WORK*

• x - int = (4, 0)

  y-int = (0, -10)

• x-int = (5, 0)

  y-int = (0, 2)

• x - int = (5, 0)

  y int = (0, -2)

• x -int = (-4, 0)

  y -int = (0, -10)
