Ethan tired to write an equation of the linear table but made a mistake. Need help it’s due today!?!?

Given:

The table for a linear function.

To find:

The equation of the linear function.

Solution:

If a linear function passes through two points, then the equation of linear function is:

Consider any two points from the given table. Let the two points are (2,-2) and (4,0). So, the equation of linear function is

Subtracting 2 from both sides.

So, Ethan 's made a mistake. The sign between x and 4 must be negative but in Ethan's equation it is a positive sign, which is not correct.

Therefore, the required linear equation is .

so, converting firstly the mixed fractions to improper fractions and then "adding".

i think the answer is 90 hope this
