X- 0 1 2 3 4 5 6
Y- -7 -4 -1 2 5 8 11
this is a x and y table
I need to find out wat the rule is to get y.
So the equation would start out like:
Y=??????
wat do u need to do with x to get y?
and I need help badly!
so please!
It looks to me for each increase in x, one will get an increase in y of 3, and at x=0 y is -7
y= 3x-7 ? check that
OMG!
thank you sooo much!
genius!
it works by the way!!!
The thing is what is the famous old saying about building a fire in a kayak and pages 55

To find the rule or equation that relates the values of x and y, we need to look for a pattern or relationship between the two sets of numbers.
Looking at the table, we can see that as the values of x increase by 1, the corresponding values of y increase by 3. This suggests that there is a linear relationship between x and y.
To determine the equation, we can use the slope-intercept form of a linear equation, which is:
y = mx + b
where m represents the slope and b represents the y-intercept.
To find the slope (m), we can choose any two points from the table. Let's take the points (0, -7) and (1, -4):
m = (y2 - y1) / (x2 - x1)
= (-4 - (-7)) / (1 - 0)
= 3 / 1
= 3
So the slope (m) is 3.
Next, we can substitute the values of one of the points (let's take (0, -7)) and the slope (m) into the equation to find the y-intercept (b):
-7 = 3(0) + b
-7 = 0 + b
b = -7
Now that we have the values of m and b, we can write the equation:
y = 3x - 7
Therefore, the rule is:
Y = 3X - 7
