A line in the xy-plane with a slope of m and a y-intercept of 0, = + ^ bh can be defined by an equation in the form y mx b. It’s given that line r 0,6 = has a slope of 4 and passes through the point ^ h. It follows that m 4 and = = + b 6. Substituting 4 for m and 6 for b in the equation y mx b yields =4 +6 =4 +6 y x . Therefore, the equation y x defines line r. 43 SAT PRACTICE TEST #5 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2 - Choice A is incorrect. This equation defines a line that has a slope of 6, not 4, 0,4 0,6 and passes through the point ^ h, not ^ h. Choice B is incorrect. This equation 0,4 defines a line that has a slope of 6, not 4, and passes through the point ^ h, not 0,6 ^ h. Choice C is incorrect. This equation defines a line that passes through the 0,-6 0,6 point ^ h, not ^ h.</p>","correct_answer":["D"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[{"label":"A","content_html":"<p>y = −6x+4</p>","ord":0},{"label":"B","content_html":"<p>y = 6x+4 = 4x−6</p>","ord":1},{"label":"C","content_html":"<p>y = 4x+6</p>","ord":2},{"label":"D","content_html":"<p>y</p>","ord":3}],"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.
