To match a graph with an equation you need to check the slope and the y-intercept. The slope is the number in front of the x and the y-intercept is the number without a letter. In this case the y-intercept is -2 and the slope is $\frac{5}{3}$. a positive slope means that the line goes upwards from left to right. a is the only graph that fits to these conditions.
