Addison painted her room. she had 50 square meters to paint, and she painted at a constant rate. after 2 hours of painting, she had 35 square meters left. let a(t), denote the area to paint a (measured in square meters) as a function of time t (measured in hours). answer !

The function can be determined by treating the two scenarios as two points since Addison paints at a constant rate. The equation can be obtained using the two-point form: (y-y1) = [(y2-y1)/(x2-x1)] (x-x1), where y refers to the area to be painted and x to the time elapsed. Substituting (x1, y1) as (0, 50) and (x2, y2), as (2, 35). The area to be painted is expressed as A(t) = -7.5t +50
