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

Question

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

y=mx+b
so you can substitute (-2, 5) and the slope of -1 into it:
5= -1(-2) +b
solving for b (the y-intercept)
5=2+b
3=b
so the equation is y= -1x + 3
none of these answers are right!!?
