<span>1. m∠6=m∠8, b||c
Given
2. m∠7=m∠8
</span><span>If lines ||, corresponding angles =.
</span><span>
3. m∠6=m∠7
</span>Substitution
<span>
4. a||b </span>
If alternate interior angles equal, then lines ||.
The equation would be:
3.50 + 0.15x
x represents each 'late day'
The constant in this case is the number without the variable, making the answer A)3.
