What is the y -intercept of the graph of y = 34 x + 81 in the xy -plane?

Question

Accepted Answer

Choice A is correct. In the xy -plane, the graph of an equation in the form y = m x + b , where m and b are constants, has a slope of m and a y -intercept of ( 0 , b ) . Therefore, the y -intercept of the graph of y = 34 x + 81 is ( 0 , 81 ) . Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
