6x + 4y = 12...subtract 6x from both sides
4y = -6x + 12 ...divide both sides by 4
(4/4)y = (-6/4)x + 12/4...reduce
y = -3/2x + 4 <== y = mx + b
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )
m = = =
Since division by zero is undefined then the slope is undefined

Step-by-step explanation: There are 4 quarts in 1 gallon.
<em>Note: I am assuming we have to determine the angle 'Ф'.</em>
Answer:
The value of Ф = 22.6°
Step-by-step explanation:
Given
hypotenuse = 13
To determine:
Angle = Ф = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
so substituting adjacent = 12, hypotenuse = 13 in the equation
cos Ф = adjacent / hypotenuse
cos Ф = 12 / 13
Ф = arccos (12/13)
Ф = 22.6°
Therefore, the value of Ф = 22.6°
