Two quantities are related, as shown in the table
x y
2 2
4 5
6 8
8 11

which equation represents the relationship?

y=3/2x+2
y=3/2x
y=3/2x-1
y=3x+2

First, take two points, and find the slope.



So now we have an equation:

y = 3/2x + b

Plug in the point (2,2) and solve for b.

2 = (3/2)(2) + b
2 = 3 + b
b = -1

The final equation that represents the relationship is y = 3/2x - 1.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
