Write an equation in slope intercept form for each table
x -2, 0, 2, 4
y 12, 6 0, -6

exactly the same procedure.
y(0) = 6
so, y = mx+6
pick any two points to get the slope. For example, (0,6) and (2,0)
the slope is -6/2 = -3
y = -3x+6
Slope would be 2 and y intercept would be 6?
slope is -6/2 = -3

He did it exactly the way I did your last problem!
To write an equation in slope-intercept form (y = mx + b) for the given table, we need to find the slope (m) and the y-intercept (b).
Step 1: Find the slope (m)
The slope (m) can be calculated using the formula:
m = (change in y) / (change in x)
Let's find the change in y and change in x between any two points. For example, let's consider the points (-2, 12) and (0, 6):
change in y = 6 - 12 = -6
change in x = 0 - (-2) = 2
So, the slope (m) between these two points is:
m = (-6) / 2 = -3
Step 2: Find the y-intercept (b)
The y-intercept (b) is the value of y when x = 0. Looking at the table, we can see that when x = 0, y = 6. So the y-intercept (b) is 6.
Now we have the slope (m) = -3 and the y-intercept (b) = 6, we can write the equation in slope-intercept form:
y = mx + b
y = -3x + 6
Therefore, the equation in slope-intercept form for the given table is y = -3x + 6.
