Question

Write the point-slope form of the equation of the line that passes through the point (1, 3) and has a slope of 2. Include your work in your final answer.

Answer 1

(y-4) = 7x - 21
y-7x = -21 + 4
y-7x = -17
7x-y-17 = 0 is the equation.

I'm not sure if this is totally correct.

Answer 2

Plug in slope and the points in y-y1=m(x-x1)
y-3=2(x-1)
