Jeremy claims that if a linear function has a slope of the same steepness and the same y-intercept as the linear function in the graph, then it must be the same function. 
 On a coordinate plane, a line goes through points (0, negative 1) and (2, 0).
 Which equation is a counterexample to Jeremy’s argument?
 y = negative one-half x minus 1
 y = negative one-half x + 1
 y = one-half x minus 1
 y = one-half x + 1
