Best ResponseYou've already chosen the best response.0Let m = the given slope, so m = 2. We now have: \(\large y = 2x + b\)

Best ResponseYou've already chosen the best response.0Now put the x and y of your point in the x and y of our equation and solve for b. \(\large y = 2x + b\) \(\large 9 = 2(10) + b\) \(\large 9 = 20 + b\) \(\large 11 = b\) Now that we know b = 11, substitute 11 for b. \(\large y = 2x + b\) \(\large y = 2 x + 11\)

Best ResponseYou've already chosen the best response.0@Nnesha is correct above. They ask for pointslope, not slopeintercept. \(\large y  y_1 = m(x  x_1) \) \(\large y  (9) = 2(x  10)\)
