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!

Car rentals involve a $130 flat fee and an additional cost of $31.67 a day what is the maximum number of days you can rent a car
Dmitry_Shevchenko [17]
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.

Solve using substitution<br><br> y=1/2x<br> x+4y=18
Aleks [24]

Answer:

The solution set is (6,3)

Step-by-step explanation:

Begin by multiplying equation 1 by 2. You'll see why in a moment

2y = 2*(1/2) x

2y = x

Substitute this value into equation 2.

2y + 4y = 18                  Combine like terms on the left

6y = 18                          Divide both sides by 6

6y/6 = 18/6                    Do the division

y = 3

To solve for x just use the top equation

y = 1/2x

3 = 1/2x                          Multiply by 2

3*2 = x

x = 6
