Answer:

y = -2x-2

Step-by-step explanation:

The equation of the line in point-slope form is expressed as:

y-y0 = m(x-x0)

m is the slope = -2

the point (x0, y0) is (1, -4)

subsitute into the equation

y -(-4) = -2(x-1)

y+4 = -2(x-1)

y+4 = -2x + 2

y = -2x +2-4

y = -2x - 2

Hence the required equation is y = -2x-2
