[3.5] In 1980, the median age at first marriage for women in the U. S. was
about 23. Presently, 40 years later, the median age has risen to 28. The
trend over time is approximately linear, and is represented by the graph
below. Write a linear equation showing how age (A) depends on time in
years (t) since 1980. (Be careful with slope: the x-axis scale is not going
by 1 year intervals) *
