Best ResponseYou've already chosen the best response.1Point slope form \[\Large yy_1 = m\left(xx_1\right)\] Plug in the given slope \[\Large yy_1 = \frac{3}{5}\left(xx_1\right)\] and the given point \[\Large y0 = \frac{3}{5}\left(x(4)\right)\] from here solve for y

Best ResponseYou've already chosen the best response.1you agree that `x(4)` turns into `x+4` right?

Best ResponseYou've already chosen the best response.1and the `y0` is simply `y`

Best ResponseYou've already chosen the best response.1So, \[\Large y0 = \frac{3}{5}\left(x(4)\right)\] \[\Large y = \frac{3}{5}\left(x+4\right)\] \[\Large y = \frac{3}{5}x+\frac{3}{5}*4 \ \ ... \ \text{distribute}\] \[\Large y = \frac{3}{5}x+\frac{3}{5}*\frac{4}{1}\] \[\Large y = \frac{3}{5}x+\frac{3*4}{5*1}\] \[\Large y = \frac{3}{5}x+\frac{12}{5}\]
