Let


A(-3,5)\ B(1,-1)

we know that

The equation of the line into point slope form is equal to


y-y1=m(x-x1)

Find the slope of the line AB

The slope is equal to


m=(y2-y1)/(x2-x1)

Substitute the values


m=(-1-5)/(1+3)


m=(-6)/(4)


m=-(3)/(2)

Find the equation of the line

Substitute the value of the slope and the point B


y-(-1)=-(3)/(2)(x-1)


y+1=-(3)/(2)(x-1)

therefore

the answer is the option


y+1=-(3)/(2)(x-1)
