Answer:
y = -3x + 7
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x
c - intercept point of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( 1 , 4) ( 2 , 1)
x1 = 1
y1 = 4
x2 = 2
y2 = 1
insert the values
m = 1 - 4 / 2 - 1
m = -3/1
m = -3
y = -3x + c
Step 2: substitute any of the two points given into the equation of a line
y = -3x + c
( 1 ,4)
x = 1
y = 4
4 = -3(1) + c
4 = -3 + c
4 + 3 = c
c = 7
Step 3: sub c into the equation
y = -3x + 7
The equation of the line is
y = -3x + 7
The final answer for this question would be.....
8.8n^2+16n+0.1
Hope this helps!!!!
Well, some integers can be irrational, but not all! :)
Answer:
Step-by-step explanation:
ratio of 216 : 64
bigger is 20 inches
so divide 20 by 216... to find the unit.. then multiply that by 64 to find the size of the other
20/216 = 0.0925925
0.0925925 * 64 =5.9259"
so about 6 inches
