Answer:


y=-5(x+2)-1


y=-5(x+3)+4

Explanation:

Two points on the line are (-3, 4) and (-2, -1)

Therefore:


\textsf{let}\:(x_1,y_1)=(-3,4)


\textsf{let}\:(x_2,y_2)=(-2,-1)


\textsf{slope}\:(m)=(y_2-y_1)/(x_2-x_1)=(-1-4)/(-2-(-3))=-5

Point-slope form of linear equation:
y-y_1=m(x-x_1)

Substituting point (-3, 4) in the point-slope equation:


\implies y-4=-5(x-(-3))


\implies y=-5(x+3)+4

Substituting point (-2, -1) in the point-slope equation:


\implies y-(-1)=-5(x-(-2))


\implies y=-5(x+2)-1
