First, set up your equation.
_(x+4)_ = 7
2
multiply both sides by 2 to cross out the 2 on the bottom
_(x+4)_ *2 = 7*2
2
x+4 =14
subtract 4 from both sides
x+4= 14
-4 -4
x=10

Answer:
y = 5x + 8
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 + 9 is in this form
with slope m = -
given a line with slope m then the slope of a line perpendicular to it is
= - , hence
= - 1 / - = 5
y = 5x + c ← is the partial equation
to find c substitute (- 2, - 2) into the partial equation
- 2 = - 10 + c ⇒ c = - 2 + 10 = 8
y = 5x + 8 ← equation of perpendicular line
