A coordinate plane with four quadrants shows the x and y axes ranging from negative 8 to 8 in increments of 1. An upward line with arrows on both the ends passes through the first, second, and third quadrants. The line intersects the x-axis at left parenthesis negative 1 comma 0 right parenthesis and the y-axis at left parenthesis 0 comma 3 right parenthesis.

Answer 1

Choose the second graph. It shows an upward line with y-intercept (0, −1) and x-intercept ≈ (0.3, 0), matching y = 3x − 1 (slope 3, initial value −1).
