A line parallel to the x-axis has a slope of 0. Thus, it's a horiz. line. Since it passes thru (1,5), the equation of this line is y = 5.
Paralell lines have the same slope
perpendicular lines have slopes that multiply to get -1
neither is niegher
so
y=mx+b
m=slope
x=y+2
minus 2
x-2=y
y=x-2
y=1x-2
slope is 1
y=x+3
y=1x+3
1=1
they are paralell
Hi! Did you mean to add a picture to your comment?
So you need 46 which means that you can’t have less than 46 otherwise you won’t have enough
46/10 = 4 packs + 6 more plates
If you only buy 4 packs you will have 40 plates but you need 46 so buy an extra pack.
So you will need to buy 5 packs of plates.
I hope this helps :)
what's the question? you only put a formula
