Match the correct equation with the graph. y = -3x + 4 y = 5/2x + 5 y = -2/5x + 2 y = -3/2x + 2 x = 4

    It means whenever the graph touches the y-axis. Look at the graph you have provided and tell me where does your graph touch (intercept) the y-axis.

    Good. So which of the options in the question say that the equation touches at 5?

    Ok, you're close but listen. Whenever you see an equation of this form. y = mx + b Where m=(-2/5) and b = 2. You know that b is always the y-intercept. Now check them again and tell me. What do you think? Since b=2 here, it means that the graph touches at 2.

    so it would be this right? y = 5/2x + 5
