The first question is non-linear because it is an exponential equation, which is a curved line on a graph.
The second question is linear because you gain 5 every week, which is a straight line.
Answer:
Perpendicular bisector
Step-by-step explanation:
The construction is of a perpendicular bisector, because the line in bisected and the angle formed by the bisector is a right angle.
Take 1/2 of liear coefient, and square it
-18/2=-9, (-9)^2=81
add 81
factors to (y-9)²
Well first we need to make a function, this is increasing proportionally so we know the equation will be
Now its increasing by 6 for each step in x so
If we plug in when x = 1 and y = 2(the first given term)
Now the arithmetic sequence can sbe represented by
If you plug in 18, well get the 18th term
The 18th term is 104
