    Answer:

    y = 2x – 13

    Step-by-step explanation:

    The equation of a line in slope- intercept form is

    y = mx + b ( m is the slope and b the y- intercept )

    Here m = 2 , then

    y = 2x + b ← is the partial equation

    To find b substitute (5, – 3) into the partial equation

    – 3 = 10 + b ⇒ b = – 3 – 10 = – 13

    y = 2x – 13 ← equation of line
