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)

aripotta · Answer

y - y1 = m(x - x1)

our point is (-2,5) so -2 would be x1 and 5 would be y1

aripotta · Answer

and -1 is m. so now just plug those in

i dont follow

aripotta · Answer

y - y1 = m(x - x1) is point-slope form.

they gave us a point (-2,5) and the slope, -1. all coordinates are setup as (x,y)

so x1 would be -2, y1 would be 5, and m would be -1.

just substitute those numbers for the corresponding variable, and there you go
