Answer:
y = x + 5
Step-by-step explanation:
As we progress, to the right, from (−2, 3) to (2, 7), x increases by 4 and y increses by 4 also. Thus, the slope of this line is m = 4/4 = 1.
The slope-intercept form of the equation of a straight line is y = mx + b.
Substituting 2 for x, 7 for y and 1 for m, we get 7 = 1(2) + b. Then b = 5, and the desired equation is y = x + 5.

Step-by-step explanation:
The 1st cylinder used to fill the pitcher has:
height:
h = 9 in
radius:
r = r
The volume of a cylinder is given by:
Therefore, the volume of the 1st cylinder is
We are told that the water inside this cylinder can fill a certain pitcher, so this is also the volume of the pitcher.
Then, we have a second cylinder, which has height
h = 9 in
and radius
r' = 2r
So the volume of this cylinder is
This means that the number of pitchers that can be filled by this 2nd cylinder is
length, l = 8.5ft
width, w
perimeter, p = 2(l+w) < 26...eqn 1
subst for l = 8.5 in eqn 1
p = 2(8.5+w) <26
expanding eqn... 2(8.5) + 2w < 26
fence length is 26ft therefore perimeter must be less than or equal (<)to 26
The greatest common factor is 2x
