The equation below is written in point-slope form. y+4+2(x-1)

Which point below was used to write the equation?

( 4, -1)
(1, -4)
( -4, 1)
(-1,4)

B

Step-by-step explanation:

To put an equation in point slope form, use the equation y-y1=m(x-x2)

If the equation is y-(-4)=2(x-(1))

Then the x value must be 1 and the y value must be -4. The answer is (1,-4)
