Based on these data, the United States abortion rate (number of abortions per 1000 women) can be estimated by the linear function R(x) = −0.58x + 23.9 where x is the year since 1990 and R(x) is the abortion rate. (a) Based on this function, is the rate increasing or decreasing? The slope is , so the rate is . (b) Find the estimated abortion rate for 2007 and for 2017. 2007 abortions per 1000 women 2017 abortions per 1000 women (c) Estimate the year when the abortion rate will be 10.
