2. Count the number of terms.
3. Check to be sure each factor is prime, if not, repeat 1-3.
4. Check by multiplying the factors out to see if you get the original polynomial.
I think so It’s linear yes
Y=-2/3x + 4 would be an equation that would fit
Check the picture below.
those angles in red are alternate interior with the angles at A and D, therefore, equal.
