7. Use the data in each table to write a linear function using function notation

According to the tables, the linear functions are given by:

A linear function is modeled by:

In which:

Item 7:

From x = -3 to x = 1, when x changes by 4, y changes by 0.8, hence the slope is:

.

Then:

When x = 1, y = 0.2, which is used to find b. Hence:

Hence, .

Item 8:

From x = -5 to x = -2, when x changes by 3, y changes by 9, hence the slope is:

.

Then:

When x = 4, y = 17, which is used to find b. Hence:

Hence, .

Item 9:

From x = -5 to x = -2, when x changes by 3, y changes by -6, hence the slope is:

.

Then:

When x = 8, y = -18, which is used to find b. Hence:

Hence, .

your answer is the frist one

hop i

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
