Question

using point-slope form, write the equation of the line that passes through the point, (-1/2,1/2) and has a slope of -1.

a. y-1/2=-x-1/2
b. y-1/2=-x+1/2
c. y+1/2=-x-1/2
d. y+1/2=-x+1/2

Answer 1

b

Answer 2

if line of slope m passes through point (h,k) the equation can be written as:
\[\Large y-k=m \left( x-h \right)\]
