The coordinate set (0, 0), (2, 1), (4, 2), (6, 3) represents a straight line. Since the first point is (0, 0) the y-intercept is 0. Now, lets solve for the slope (we can use any of the four points to solve).
Slope formula: y2-y1/x2-x1
= 2-1/4-1
= 1/2
Now that we know what the slope is, we can write the equation of the line.
Slope intercept form: y = mx + b (m = slope and b = y-intercept)
y = 1/2x
Lets find the exponential equation for the line.
y = ab²
1 = ab²
1/a = ab²/a
1/a = b²
√1/a = √b²
√1/a = b

Answer:
A = 
. r^2
If A = 9ft^2
. r^2 = 9ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)

Answer:
that puts the solution in the form ...
variable is ...
Step-by-step explanation:
It isn't always.
__
Often, we like to have a solution be in the form ...
variable is ...
So, for an inequality, that puts the variable on the left:
x > 3
y < 27
__
Personally, I like to see the answer in a form that has the variable and its values in the same relation as on a number line. This means, my preferred inequality symbols are < or ≤, since those have the smaller numbers on the left. I would write the first example above as ...
3 < x
showing that the shaded portion of the number line (representing possible values of the variable) is to the right of the open circle at 3. For me, it is more mental effort to translate x > 3 to the same image.
