Best ResponseYou've already chosen the best response.1you 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

Best ResponseYou've already chosen the best response.1no... 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 207=b ...whats b=?

Best ResponseYou've already chosen the best response.1yes 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"
