Correct answer only enter an inequality that represents the graph in the box.

1. We need to find the equation of the line.

y = mx + b

b = - 1

m = rise/run = 3/1

y= 3x - 1

2. The colored part is under the line, so it should be

y ≤ 3x - 1

Check:

Take points that is in the colored area. For example (2,0).

y ≤ 3x - 1,  

0 ≤ 3*2 - 1, 0≤ 5. True.

y ≤ 3x - 1.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
