<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>
3y = 4x + 39
y = 
+ 
When x is 0, y = 0(x) + , so the y intercept is
<h3>Next, the slope is simply the number in front of the x, </h3>
So can be rearranged to 
, so the slope would be 
.

Answer:
1/7
Step-by-step explanation:
Plug in 2 for m, and 14 for n in the expression:
m/n = 2/14
Simplify. Factor out common factors from both the numerator and denominator:
(2/14)/(2/2) = 1/7
1/7 is your answer.

Answer:
Breadth = 8 cm
Length = 17 cm
Step-by-step explanation:
Given rectangle:
Breadth = x cm
Length = x + 9 cm
Area = length * breadth
= x * (x + 9)
= x² + 9x
Rectangle with length and breadth increased:
Breadth = x + 3 cm
Length = x + 9 + 3 = x + 12 cm
Area = 84 + (x² + 9x) cm²
(x +3) * (x +12) = 84 + x² + 9x
Use FOIL method
x*x + x*12 + 3*x + 3*12 = 84 + x² + 9x
x² + 12x + 3x + 36 = 84 + x² + 9x {add the like terms}
x² + 15x + 36 = 84 + x² + 9x
x² + 15x + 36 - 84 - x² - 9x = 0
6x - 48 = 0
6x = 48
x = 48/6
x = 8
Breadth = x = 8 cm
Length = x + 9 = 8 +9 = 17 cm
