Answer:

C y = 4x + 5

Step-by-step explanation:

use y = mx + b

we need m and b to complete the equation.

m = slope

b = y-intercept (when x =0)

(0, 5) is the y-intercept because that's when x = 0

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{9-5}{1-0} = \frac{4}{1} = 4$

slope is 4

so... y = 4x + 5

Which ordered pair lies on the graph of the function y= -2x +1

ratelena [41]

Note: You did not mention the ordered pair choices. So, I am letting you clear your concept about taking some sample ordered pairs which anyways would clear your concept.

Answer:

The ordered pairs (1/2, 0) and (0, 1) are on the graph.

The graph is also attached.

Step-by-step explanation:

Given the function

$y= -2x +1$

Any ordered pair which may satisfy the equation would lie on the graph.

Let us determine the x and y-intercepts.

Determining the x-intercept

We know that the x-intercept can be determined by setting y=0, and the solving for x. so

$y= -2x +1$

0 = -2x+1

-2x = -1

Divide both sides by -2

x = 1/2

Thus, the x-intercept is (1/2, 0)

Determining the y-intercept

We know that the y-intercept can be determined by setting x=0, and the solving for y. so

$y= -2x +1$

y = -2(0)+1

y = 1

Thus, the x-intercept is (0, 1)

Thus, the ordered pairs (1/2, 0) and (0, 1) are on the graph.

The graph is also attached.

Please help explain each problem thank you have a great day

Part A. 250+45a=t
That's because 'a' is the variable in which we don't know how many appointments she will have. 'a' times the $45 would be in the equation. Then you would have to add the $250 for the tests and medicines.So 250+45a=t
Part B.(250+45a)-(25%*t).
That's because the first set in parentheses is the total cost. You would have to subtract that buy the discount times the total cost which represents the the second set of the equation.:)
Part C.25%*6 appointments equals 1.5. You have to solve (250+45) and then multiply 25%*6.That product plus (250+45) would be your final answer.U won't tell you the answer because it would help.U would need explanation.This is how I would answer the question.Hope this helped
