Which equation represents the relationship shown in the table below?

y=3x -7

Step-by-step explanation:

You are familiar with the y = mx + b, or slope intercept form. The "b" value is the y intercept, which is where the line intersects with the y axis, and where x is 0. In this case, it is -7. So let's put that back in the equation: y = mx + (-7), or y = mx -7. Now, since we have multiple values, we can use the equation y2 -y1 over x2 - x1 tyo find the value of m, the slope. Lets pick 2 consecutive values on the table. How about...x=2, y=-1 and x=4, y=5. We have 2 Y values, 5 and -1. So in our formula:

y2 - y1 = 5 - (-1) = 6

x2 - x1  = 4 - 2    = 2

6/2 = 3, so the value of m is 3. Put it back in the equation, and we have y = 3x-7. Hope this helps!

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

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!
