y=-3x+7
Step-by-step explanation:
Parallel means the lines have the same slope.
So they practically give you the slope as -3
Now we can use the form of an equation of a line
Y=mx+b
now we have m- the slope we just need to plug in the coordinate values given- (2,1)
Y=-3x+b
1=(-3·2)+b
1=-6+b
b=7
now we add to our original equation
we know m= -3
we know b=7
that's all we need
substitute
y=mx+b
becomes
y=-3x+7
Hope this helps

here's ur answer..
atq, A 1200 sq ft house is advertised for sale at a price of 96000.
we have to find the cost per sq ft.
area of the house is given = 1200ft²
and price = 96000
therefore cost per ft² = 96000/1200
= 80
Cheers!!
