Since the relationship between x and y is linear, if two points on the graph make a linear equation true, then the equation represents the 40 relationship. Substituting 0 for x and for y in the equation in choice B, 43 SAT PRACTICE TEST #10 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2 8 +12 =480 8 0 +12 40 =480 480=480 x y , yields ^ h ^ h , or , which is true. 60 8 +12 =480 Substituting for x and 0 for y in the equation x y yields 8 60 +12 0 =480 480=480 ^ h ^ h , or , which is true. Therefore, the equation 8 +12 =480 x y represents the relationship between x and y. 0,40 Choice A is incorrect. The point ^ h is not on the graph of this equation, since 40=8 0 +12 40=12 0,40 ^ h , or , is not true. Choice C is incorrect. The point ^ h is 40=12 0 +8 40=8 not on the graph of this equation, since ^ h , or , is not true. 0,40 Choice D is incorrect.
