Answer: y = (2/3)x + 2

Step-by-step explanation: We have a line that passes trough the points (0, -1) and (3, 1)

The slope of this line that passes trough the points (x1,y1) and (x2,y2) is:

s = (y2 - y1)/(x2 - x1)

s = ( 1 - (-1))/(3 - 0) = 2/3

So we know that this line has the shape:

Y1(x) = 2/3x + b

where b is the y intercept.

In order to find the value of b, we can do:

Y1(0) = -1 = (2/3)*0 + b = b

so we have that b = -1, and the equation of the line is:

y1(x) = (2/3)*x - 1

Now, we want to find another parallel line that passes through the point (-3,0)

because this new line is parallel to the one we previous had, their slopes must be equal, then the equation of our new line is:

Y2(x)= (2/3)x + c

and we need to find the value of c.

Y2(-3) = 0 = (2/3)*-3 + c = -2 + c = 0

c = 2

then the equation is:

Y2(x) = (2/3)x + 2

1 of 5<br>What is the nth term rule of the linear sequence below?<br>2,5, 8, 11, 14, ...<br>w<br>Tn​
Alika [10]

Answer: 3n-1

The difference between each of the numbers is 3.  This means that we have 3n.

If we assume that for the first number n=1, then 3*1=3, but the value we have is 2. This means that we must subtract 1 to get from 3 to 2.

- 5.8c + 4.2 - 3.1 + 1.4c − 5.8c + 4.2 − 3.1 + 1.4c
Cerrena [4.2K]

Answer:

-8.8c + 2.2 OR SOLVED c = 0.25

Step-by-step explanation:

<u>Step 1:  Combine like terms</u>

- 5.8c + 4.2 - 3.1 + 1.4c − 5.8c + 4.2 − 3.1 + 1.4c

<em>-8.8c + 2.2</em>

<em />

<u>Step 2:  If needed solve for c</u>

-8.8c + 2.2 - 2.2 = 0 - 2.2

-8.8c / -8.8 = -2.2 / -8.8

<em>c = 0.25</em>

<em />

Answer:  -8.8c + 2.2 OR SOLVED c = 0.25

Which of the following ordered pairs represents the solution to the system of equations below?
expeople1 [14]
<span>-3x + 2y = 2  eq (1)

  7x - 3y = 7    eq (2)

Mutiply eq (1) by 3 and eq (2) by 2:

-9x + 6y = 6

14x - 6y = 14

Add th two new equations:

-9x + 14x = 6 + 14

=> 5x = 20

=> x = 20/5

=> x = 4

Now from eq (1)

-3(4) + 2y = 2

=> 2y = 2 + 12

=> 2y = 14

=> y = 14 / 2

=> y = 7

So the ordered pair is (4,7)

Answer: option B. (4,7)
