The answer is D. It's always Rise over Run. So the slope would be 2/1 Or 2.
The variable is d, so the coefficient is 1/4. Factor out 1/4 and you are left with (d-3).
X + 3y = 9
3x - 3y = -13
--------------add
4x = - 4
x = -4/4
x = -1
x + 3y = 9
-1 + 3y = 9
3y = 9 + 1
3y = 10
y = 10/3
solution (-1,10/3)
Step-by-step explanation:
x² + 4x + 3
(x+1)(x+3)
