The difference between 3 and 6 is 6-3 =3.
The difference between 6 and 9 is 9-6 =3.
The difference between 9 and 12 is 12-9 =3.
The difference between 12 and 15 is 15-12 =3.
The difference between 15 and 18 is 18-15 =3.
Recall that linear have equal differences.
We get an equal difference between each value.
The form of the equation is
Hence the given is linear.

AB is parallel to CD, and EF is perpendicular to AB
The number of 90° angles formed by the intersections of Ef and the two parallel lines AB and CD is ____
Answer:
The number of 90° angle formed = 8 angles
Step-by-step explanation:
From the question and attached diagram, the following information is given:
AB is parallel to CD
EF is perpendicular to AB
Required: number of 90° angles formed by the intersection of the perpendicular line and the parallel lines.
<em>Note, the angle formed between a line and a perpendicular line = 90°</em>
From the diagram:
Number of 90° angle formed by intersection of perpendicular line EF and line AB = ∠1, ∠2, ∠3 and ∠4 = 4 angles
Number of 90° angle formed by intersection of perpendicular line EF and line CD = ∠5, ∠6, ∠7 and ∠8 = 4 angles
Total 90° angles formed by perpendicular line with lines = ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, and ∠8 = 8 angles
