Remark
You can just look at the graph to find out the y intercept. The y intercept is the point where x = 0. The point for the y intercept is (0,-2). So B is definitely wrong.
To get the slope, you can just use the x intercept which is (-3,0)
When y = 0, x = - 3. We need to do a little calculation to get the slope.
So far what we have is
y = mx - 2
y = 0
x = -3
0 = m(-3) - 2 Add 2 to both sides.
2 = m(-3) Divide by - 3
2/-3 = m
Now let's see what we have.
y = -2/3x - 2
C is the correct answer
Draw arcs on either side of a given point on the line
Answer: 6.25
Step-by-step explanation: simple division
Answer:0.81
Step-by-step explanation:
A: Given teenager owns a skateboard. P(A) = 0.48
B: Given teenager owns roller blades. P(B) = ? - we dont know and dont need
AB: Given teenager owns a skateboard and roller blades. P(AB) = 0.39
P(B/A) = P(AB)/P(A) = 0.39/0.48 = 0.8125
