Find slope as negative reciprocal of 2 => m=-1/2
y=mx + b
8=5(-1/2) +b
b=21/2
y= -1/2x +21/2
Answer:

Step-by-step explanation:
We want to find equation of a circle with center (-4,6) and radius 9cm.
The equation of a circle with center (h,k) and radius
units is given by;

We substitute the radius and the center to obtain;

The required equation is:

Step-by-step explanation:
Answer:
A) slope is -12
B)The rate of change is constant because for every 5 seconds the change is the same. For every 5 seconds, the height decreases by 60ft. The equation is y=12x+1210

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a righ rectangular prism
Given data
Length of prism l= 12inches
Width of prism w= 7 inches
Height of prism h= 5 inches
We know that the volume of a rectangular prism is expressed as
Volume =l*w*h
Volume = 12*7*5= 420in³
