X= (y-21)/2 is the age of Gorans
Answer:
y= -3/4x-1
Step-by-step explanation:
The points are (8,-7) and (0,-1)
The slope is the change in Y over the change in X, so you have -3/4 as your slope.
Then, you have y=-3/4x+b
You substitute either (8,-7) or (0,-1) for X and Y in the equation, and solve it, giving you -1 for B
Pretty sure that both A and B are correct
Answer:
b. x=10
x is greater than or equal to 8 so I believe that 10 is the best answer
Answer:
Step-by-step explanation:
1. (-4, -2) (4, 0)
(0 + 2)/(4 + 4)= 2/8= 1/4
2. (-1, 2) (1, -3) = (-3 - 2)/(1 + 1) = -5/2
3. (-2, 3) (0, 0) = (0 - 3)/(0 + 2) = -3/2
4. (1, 1) (3,2) = (2 - 1)/(3 - 1)= 1/2
