Answer :
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{54 - 6}{16 - 4} = \frac{48}{12} = 4[/tex]
[tex]y - y_1 = m(x - x_1) \\ y - 6 = 4(x - 4) \\ y - 6 = 4(x) - 4(4) \\ y - 6 = 4x - 16 \\ y = 4x - 10 [/tex]
[tex]y - y_1 = m(x - x_1) \\ y - 6 = 4(x - 4) \\ y - 6 = 4(x) - 4(4) \\ y - 6 = 4x - 16 \\ y = 4x - 10 [/tex]
