Answer:
D) 2
Step-by-step explanation:
Use the following slope formula:
<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (4 , 1)
(x₂ , y₂) = (1 , -5)
Plug in the corresponding numbers to the corresponding variables:
<em>m</em> = (-5 - 1)/(1 - 4)
Simplify. Remember to follow PEMDAS. First subtract, then divide:
<em>m</em> = (-5 - 1)/(1 - 4)
<em>m</em> = (-6)/(-3)
<em>m</em> = 2
D) 2 is your answer.

Answer:
3 = 6
Step-by-step explanation:
Y = -1/3x + 5....slope here is -1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So ur perpendicular line will have a slope of 3.
y = 3x....has a slope of 3, so this is perpendicular.
3x - y = 2.....y = 3x- 2.....has a slope of 3 and is therefore perpendicular
3x - y = 6.....y = 3x - 6...has a slope of 3 and is perpendicular
Answer:
-3
Step-by-step explanation:
Note the parts of the equation:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
In this case: y = 4x - 3
x = x
y = y
m = slope = 4
b = y-intercept = -3
