Answer:
Given:
5 pounds rice cost $2.49
To Find:
Cost of 9 pounds rice
Step-by-step explanation:
5 pounds rice cost $2.49
1 pound rice will cost $ 
So,
9 pounds rice cost = 1 pound rice cost × 9
= $ 
= $0.498 × 9
= $4.482
The answer in slope intercept form is y = 6x-11
If you want the answer in standard form, then it would be 6x-y =11
notes:
* Slope intercept form is y = mx+b
* Standard form is Ax+By = C
=====================================
Explanation:
The given slope is m = 6
The line goes through (x,y) = (3,7)
Plug those three values into the equation below. Isolate b
y = mx+b
7 = 6*3+b
7 = 18+b
7-18 = 18+b-18 ... subtract 18 from both sides
-11 = b
b = -11
So because m = 6 and b = -11, this means y = mx+b turns into y = 6x-11
The answer in slope intercept form is y = 6x-11
To convert to standard form Ax+By = C, we just have to get all the x and y terms together on the same side. I'm going to move the y term to the right side and move the 11 to the left side
y = 6x-11
y+11 = 6x-11+11
y+11 = 6x
y+11-y = 6x-y
11 = 6x-y
6x-y = 11
The answer in standard form is
6x-y = 11
which is a different way to write the same line

The average cost of a two-bedroom apartment in the city will be about $1135
Step-by-step explanation:
The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.
Given that the average cost of one-bedroom apartment is $724, then using this value for x
yˆ=1.377*724+137.763 = 1134.711
This value is approximately $ 1135
