Which graph represents the given system of equations?
Explanation
Choice A is correct. The graph of a quadratic equation in the form has its vertex at . The first equation in the given system of equations is , so the graph of this quadratic equation has its vertex at . The graph of a linear equation of the form has a slope of and a y-intercept at . The second equation in the given system of equations is , so the graph of this linear equation has a slope of and a y-intercept at . Of the choices, only choice A has the graph of a quadratic equation with its vertex at and the graph of a linear equation with a slope of and a y-intercept at .
Choice B is incorrect. This graph represents a system in which the second equation is , not .
Choice C is incorrect. This graph represents a system in which the first equation is , not .
Choice D is incorrect. This graph represents a system in which the first equation is , not , and the second equation is , not .
