Answer:
y = 2x - 11
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 = - x + 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 2 , then
y = 2x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = 16 + c ⇒ c = 5 - 16 = - 11
y = 2x - 11 ← equation of perpendicular line
Answer: s=36
Step-by-step explanation:
To solve for s, we can use our algebraic properties to solve.
[subtract both sides by 14]
[multiply both sides by 3]
