We observe that a line will pass through 3 points, but to find a slope we only need two.
We see that it passes through points (assuming the scale of graph is 1 : 1) 
and 
.
We can use slope formula that applies for any line and produce the same slope for any two different points on the line
So the slope is -1 also it intersects y-axis at 
so the general form of the linear function is
That is in your case
Hope this helps.
Answer:
divide the number of miles you tried by the number of miles per ga;
738/18 = 41 gluons.
now multiply 41 x $2.24 = $9q.84
Hope this helps you with your question
Answer:
= 486 in²
Step-by-step explanation:
Linear scale factor = Image distance/object distance
Therefore; Linear scale factor = OL'/OL
= 54/ 12
= 9/2
Area scale factor is equivalent to the square of linear scale factor
Thus;
Area scale factor = (9/2)²
= 81/4
Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle
Area of the smaller rectangle = 4 ×6 = 24 in²
Therefore;
Area of enlarged or larger pic = 81/4× 24
<u>= 486 in²</u>
A = LW
A = 66
L = 2W + 1
66 = W(2W + 1)
66 = 2W^2 + W
2W^2 + W - 66 = 0
(2W - 11)(W + 6) = 0
2W - 11 = 0
2W = 11
W = 11/2
W = 5.5
W + 6 = 0
W = -6 (this is an extraneous solution...it will not work)
L = 2W + 1 = 2(5.5) + 1 = 12
so ur dimensions are : Length = 12m and width = 5.5m
