The answer is 3) 5+r/14
Let's go segment by segment:
<span>"five plus" means addition, so we have 5 +
</span><span>"the quotient of r and 14" is the division result, so sign / must be present: 14/r
</span>
Therefore "five plus the quotient of r and 14" is 5 + 14/r
<span> y-4=-8(x-1) is linear
===================
</span><span>y=x4 is non linear, it is a parabola or a curved line
===================
</span><span>y-x2=4.5 is non linear as it is curved
===================
</span><span>3x + 5y = 15 is linear</span>
