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

Your digital camera has a memory card that has a total of 512 megabytes. You can take pictures at two resolutions, a low resolution (x) which requires 4 mb per photo and a high resolution (y) which requires 8 mb per photo. After writing an equation to model the situation, determine how many high resolution photo can you take, if you have already taken 50 low resolutions? JUST WRITE THE NUMBER.

Draw the graph of 3x - 5y = 30. Please draw as neat as possible so I can understand your graph.

Draw the graph of 6x + 8y = -24. Please draw as neat as possible so I can understand your graph.
