Step-by-step explanation:
The markup percent is $15
Step-by-step explanation:
<h2>Hey let solve this!!!</h2>
the formular we're to use is the point slope formula
<h2>y - y1 = m( x - x1 ) </h2>
<h2>from y = - 3x +1 </h2>
SLOPE = -3
and x1= -5 y1 = -6
HENCE
Y - Y1 = M (X- X1)
y-(-6) = -3( x--5)
y+ 6 = -3 (x+5 )
y+6 = -3x -15
y= -3x-15-6
y= -3x -21
