Step-by-step explanation:
(1)
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = = -
(2)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
note the line crosses the y- axis at (0, 3) ⇒ c = 3
y = - x + 3 ← equation of line

The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?
Solution:
Circumference (C) of the circle can be written as:
Using this value of radius, we can find the Area(A) of the circle.
Therefore, area of the circle having a circumference of 18π inches will be 81π inches²
