Answer: The equation of the trend line is y = -2x + 24.
First, we need to find the slope. The slope is the change in y over the change in x between the points. Our points move down 4 units while moving right 2 units. So our slope would be -4/2 or just -2.
Second, we need to find the y-intercept. We are lucky because the y-intercept can be see clearly in the graph. It is (0, 24).
We can put the slope and y-intercept together to get the equation:
y = -2x + 24.
Answer:
6
Step-by-step explanation:
set x=0 and solve
(0+4)(0+2)=y
y=6
Answer:
b = 0.1
Step-by-step explanation:
1) add -1.5 at both members
1.34-1.5 = -1.6b+1.5-1.5
-0.16 = -1.6b
2) divide both members by -1.6
b = 0.1
Answer:
247,085 doctors in total
Step-by-step explanation:
55,100 = 22.3℅ ÷22.3
2,471 = 1℅
2471.85x100 = 247,085 doctors
To check I'll do 247,085÷100 = 2,470.85 = 1℅
2,470.85 × 22.3 = 55,099.955 which would round up to 51,000.
