Hello!
Firstly, we can complete the linear function. To complete it, we need to find the y-intercept of the equation. To find it, we use the equation: y = -2/3x + b, substitute the point (2, 1) into the equation, and solve for b.
1 = -2/3(2) + b
1 = -4/3 + b (add 4/3 to both sides)
b = 7/3
The completed linear equation is: y = -2/3x + 7/3.
The easiest way to find the ordered pair that is on the graph is to graph the equation and label the points (the graph is posted below).
As seen on the graph, the ordered pair, (8, -3), is graphed. To prove it is correct, we can substitute the ordered pair into the linear function.
-3 = -2/3(8) + 7/3
-3 = -16/3 + 7/3
-3 = -3 | True!
Therefore, the answer is choice D, (8, -3).
I don't know any good sites with ACT practice problems, sorry and good luck!
130 is closer to 100 than 200, so it is 100
Answer:
2
Step-by-step explanation:

I was doing it wrong. You have to find 30% of $86 which is $25.80, i think, and then take it away from $86 and so the sales price is $86 - $25.80 = $60.20. Originally I only did the first bit, I forgot you have to take it away. sorry hope this helps more now.
Rs 100 of the average total cost is made up of variable costs.
Step-by-step explanation:
Given:
Number of output the firm produces= 7 units
Average cost of the output= Rs. 150
fixed factors of production = Rs.350
To Find:
How much of the average total cost is made up of variable costs=?
Solution:
we know that,
Average total cost= total cost/ number of output units produced
substituting the values, we get
Total cost= 1050
we know that Total fixed cost = 350
Total cost = Total fixed cost + Total variable cost
plug in the known values.
1050= 350 + Total variable cost
Total variable cost = 1050-350
Total variable cost =700
For 7th unit 
= 100
