It’s given that function f is defined bfy x x2 3. = ( ) Therefore, the equation representing the graph of y f x in the xy-plane is = + = + y 2x 3, and the graph is a line. For a linear equation in the form y mx b, m = + represents the slope of the line. Since the value of m in the equation y 2x 3 is 2, the slope of the line defined by function f is 2. It’s given that line j is parallel to the line defined by function f. The slopes of parallel lines are equal. Therefore, the slope of line j is also 2.</p>","correct_answer":["2"],"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.
