write an equation in point slope form y-y1 = m(x-x1) of the line through points (4,-4) and (1.2) use (4,-4) as the point (x1,y1)

Answer 1

Compute the slope between (4,-4) and (1,2) = (2--4)/(1-4) = -2, so m = 2

equation of line using 4, -4 as x1,y1:

y+4 = -2(x-4)

Answer 2

Assuming 1.2 is the slope

y + 4 = 1.2(x - 4)
