Question

Write an equation of a line in point slope form that has a slope of -2 and passes through (5,-1)?
A. y + 1 = -2(x-5)
B. y - 1= -2(x-5)
C. y - 5 = -2(x +1 )
D. y-5 = -2(x-1)

Answer 1

using the point slope formula

\[y - y _{1}= m(x - x _{1})\]

\[y _{1} = -1......x _{1} = 5\]

and m = -2

just substitute to find the equation
