Question

Write in Point- Slope Form the equation of the line that passes through ( 2,-1) and has a slope of -4.

Answer 1

Answer:

(2,-1)=(x1, y1)

m=slope= -4

the eqation of line is

y-y1=m(x-x1)

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

y+1= -4*x-(-4)*2                                                                  (-- is + at left side)

y+1= -4x+8                                                                          (-- is +)

y=-4x+8-1

y=-4x+7 , therefore this is the equation of the line.
