The answer is y = x - 4. The points already have the y-intercept which is -4, and to solve for the slope you must do 6-0 divided by 2 - (-4) which is equal to 6/6 which is equal to 1.
Answer:
As e is point between df. So we can write df as
df = de + ef
As given df = 78 , de = 5x - 9 , ef = 2x + 10.
So we can write
78 = 5x - 9 + 2x + 10
78 = 7x + 1
On subtracting 1 on booth side
78 - 1 = 7x +1 - 1
77 = 7x
On dividing both side by 7.
11 = x
So x = 11.
So ef = 2x + 10 = 2*11 + 10 = 22 + 10 = 32

Answer:
Both graphs can be used.
Step-by-step explanation:
because the time and the difficultly of the grade both depend on how long they take. Therefore it would be both graphs can be used.
Answer:
-25
Step-by-step explanation:
f(-12) means x = -12
so you just plug it in the equation and solve for x
