It shows that there is only one way to get to 10 which is by multiplying it by 1
I wish I knew but same profile pic pog
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7
answer
</span><span>parallel</span>
