The x-axis ranges from negative 10 to 10 in increments of 1. The y-axis ranges from negative 10 to 10 in increments of 1. The first point has coordinates left parenthesis negative 2 comma negative 1 right parenthesis. The second point has coordinates left parenthesis 0 comma 3 right parenthesis.

Answer 1

The points fit y = 2x + 3 (slope = 2, y-intercept = 3). The graph that shows a line through (0, 3) and (-2, -1) matches this. So choose the first graph.
