Answer:
(x+1)(x-9)
Step-by-step explanation:
x^2+x-9x-9=0
x*(x+1)-9(x+1)=0
(x+1)(x-9)=0
x+1=0
x-9=0
x=-1 and x=9
Answer:

You can write both Deals in slope inter form.
Tesla: y = 25x+75
Porsche: y=50x
Remember: slope inter form is y = mb + b
"mx" being the change in y over the change in 1 or (y1-y2/x1-x2)
"b" in the formula represents the y-axis
Answer:
slope of line parallel to given line=slope of given line
=9/2
slope of line perpendicular to given line=‐1/slope of given line
= -2/9
