Pick the third one because he tell you which graph represents a bike traveling at constant rate of 12 miles per hour
Step-by-step explanation:

Using the point C (-4,-2) and the refection rule:


<em>x = - 9</em>
- Step-by-step explanation:
<em>6x + 10 = 4x - 8</em>
<em>6x - 4x = - 10 - 8</em>
<em>2x = - 18</em>
<em>x = - 18 : 2</em>
<em>x = - 9</em>
(-1,-4) is where the equations Y=4x and x+y=-5 intersect.
