Determine if the equations represent lines that are parallel, perpendicular, or neither.

lines are parallel and m = 7

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 )

14x = 2y - 6 or

2y - 6 = 14x ( add 6 to both sides )

2y = 14x + 6 ( divide through by 2 )

y = 7x + 3 ← in slope- intercept form

with slope m = 7

------------------------------

= y - 7x or

y - 7x = ( add 7x to both sides )

y = 7x + ← in slope- intercept form

with slope m = 7

Since slopes of both lines are equal, both m = 7 then lines are parallel

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
