Ans(1):
Given equation is f(x)=-1.5x+6
we can plug any number like x=0 and x=2 to find the f(x) also called y-value
plug x=0
f(x)=-1.5x+6 =-1.5*0+6 =0+6 =6
Hence first point is (0,6)
plug x=2
f(x)=-1.5x+6 =-1.5*2+6 =-3+6 =3
Hence first point is (2,3)
now we can graph both points then join them to get final graph of f(x)=-1.5x+6
---------------------
Ans(2):
We can repeat exactly same process for f(x) = -1/2x-5.
So the final graph will look like attached picture:
The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.
<h3>What is the general equation of a circle?</h3>The equation of a circle is given by the formula,
where (a,b) is the coordinate of the center of the circle, and r is the radius of the circle.
According to the given equation, if we compare this equation with the general equation of the circle.
On observing this equation we will get that the value of (a,b) is (4,12).
Thus, The equation indicates that the center of the window is 12 feet from the ground
window span = diameter of circle
window span = 2r
= 2 × 3 (radius = 3)
= 6
Hence, The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.

Answer:
Option A) Circle.
Step-by-step explanation:
We are given the equation:
A general equation of the circle is of the form:
where (h,k) is the center of the circle and r is the radius of circle.
Comparing the two equations, we get,
Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.
