Write a linear equation to represent this situation.

Write the coordinates for each point. Write a relationship that could describe this graph.

Which ordered pair (x,y) satisfies the equation 24x + 12y = 60

A.) (3,4)B.) (6,2)C.) (1,3)D.) (-1,5)

Graph each of these coordinates to determine if the function is linear or non-linear. Also find the slope of each line.
