Answer:
y = - 1x -3
Explanation:
First you want to find the slope. you do this by dividing the change in y by the change in x.
8-1/-3-4
when you do this you get 7 over -7. therefore, the slope would be -1.
next, you want to plug this into a point-slope equation.
y-y1=m(x-x1)
y-1=-1(x-4)
now you simplify this equation into a slope intercept equation
y-1=-1(x-4)
at 1 to each side, and distribute the -1
y=-1x-4+1
simplify
y=-1x-3
