HELP ASAP! Pls and thx! Need help.

y = -3x + 22

Step-by-step explanation:

To find m, find the change in y and divide it by the change in x.

For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
