A y-intercept of a graph in the xy-plane is a point where the graph intersects the y-axis, which is a point with an x-coordinate of 0. Substituting 0 for x in the given equation yields 3 ^7 0 h=- 5 9 y+21 , or 0=- 5 9 y+21 . 21 -21=- 5 y Subtracting from both sides of this equation yields 9. Multiplying - 189=5 both sides of this equation by 9 yields y. Dividing both sides of this 189 = equation by 5 yields 5 y. Therefore, the y-coordinate of the y-intercept of the 189 graph of the given equation in the xy-plane is 5 . Note that 189/5 and 37.8 are examples of ways to enter a correct answer.</p>","correct_answer":["5"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[],"attribution":{"source_id":"cb_practice_pdf","source_name":"College Board full-length SAT practice tests (PDF)","rights_holder":"College Board","canonical_url":"https://satsuite.collegeboard.org/practice/practice-tests/paper","retrieved_from":"https://satsuite.collegeboard.org/practice/practice-tests/paper","attribution":"Full-length SAT practice tests 4–11 © College Board, published free at satsuite.collegeboard.org.","disclaimer":"Extracted from PDF layout: equations, figures and tables do not survive intact.
