That depends a lot on the school, and the ability of the students. When I was in the 9th grade, a lot of the students still had general math, with vestiges of the higher orders of math, such as Trigonometry, Geometry, and Algebra. All these were basic in nature, and not full courses in these disciplines. For those students who could handle the higher maths, Algebra was common, as well as the brightest having Geometry, and Trigonometry. The New York state school system used the delineation of Practical Local, Local, Regents, and High Regents. In reverse order, most able, able, less able, and thoroughly confused past 1+1, to handle higher orders of math, and abstract reasoning.
