Answer:
y = - 
x - 5
Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 2x + 3 is in this form with slope m = 2
given a line with slope m then the slope of a line perpendicular to it is
= - 
= -
y = - x + c ← is the partial equation
To find c substitute (- 2, - 4) into the partial equation
- 4 = 1 + c ⇒ c = - 4 - 1 = - 5
y = - x - 5 ← equation of perpendicular line
Answer: 13
Explanation:
Use Pythagorean theorem:
=> a^2 + b^2 = c^2
=> 5^2 + 12^2 = c^2
=> 25 + 144 = c^2
=> 169 = c^2
Take the square root of both sides:
=> sqrt(169) = sqrt (c^2)
=> 13 = c
