Answer:
18
Step-by-step explanation:
There are 2+3 = 5 ratio units representing 45 band members, so each ratio unit represents 45/5 = 9 band members.
The 2 ratio units of sixth graders represent 2×9 = 18 sixth grade band members.
Answer:
<em>y = (x - 4) - 4 </em>
Step-by-step explanation:
m =
(- 2, - 10)
(4 , - 4)
m =
= 1
y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>
Answer:
y = -1/2 + 2 (Slope intercept)
Step-by-step explanation:
Y-intercept is when the x-value is 0.
So the y-intercept is (0, 2)
To find slope, find two random points:
(0, 2) , (2, 1)
Slope (m) =ΔY/ΔX = -1/2 = -0.5
Equation of the line:
y = -0.5x + 2
or
y = -1/2 + 2
When x=0, y = 2
When y=0, x = 4
