Determine the equation of the line given by the graph. a) y = 2 3 x − 1 b) y = 3 2 x − 1 c) y = −2 3 x − 1 d) y = −3 2 x − 1

Step-by-step explanation:

The given graph belongs to a linear function, because it's a line.

To find its equation, we first need to find the slope of the line using two points and the formula

We are gonna use points (0,-1) and (3,1), because the lines crosses through them. Replacing these points in the formula, we have

Now, we use one points and the point-slope formula

Therefore, the right answer is A.

50

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
