Question

Can some one help me??

Answer 1

I think it’s B, because it’s not adding or subtracting in a pattern

Answer 2

Answer: Choice A

Answer for the box:   (-7/2)x+3

===================================================

Explanation:

The table shows that x = 0 leads to y = f(x) = 3. This immediately tells us the y intercept is b = 3. The y intercept occurs whenever x = 0.

To find the slope, note how each time x goes up by 2, y decreases by 7. So we can say

slope = rise/run

slope = (change in y)/(change in x)

slope = -7/2

We can write that as -3.5

If you want to apply the slope formula, then you can do so on any two points from the table. I'll pick on the first two columns

m = (y2-y1)/(x2-x1)

m = (3-10)/(0-(-2))

m = (3-10)/(0+2)

m = -7/2

m = -3.5

So we can say that y = mx+b turns into y = (-7/2)x+3 since we found m = -7/2 and b = 3

--------------------

As a check, plugging x = -2 into the equation leads to...

y = (-7/2)x+3

y = (-3.5)*(-2)+3

y = 7+3

y = 10

This verifies the first column of the table. I'll let you check the other columns.
