    you already have all the info to solve this... slope=5 so... m=5 points (x, y) so,.. x = -4 and y=-7 now sub those values into the given slope - intercept formula ... then solve for "b" which is the y intercept

    yes like this y=mx+b -7=5(-4)+b now solve for "b"

    no... first we multiply the parentheses ..we get -7=-20+b then we add 20 to both sides of the equation ...we get -7+20=-20+20+b simplify we get 20-7=b ...whats b=?

    yes and thats the y intercept now we write the equation using the slope and y intercept y=mx+b ... we just sub the value of "m" and "b"
