Answer: (-2, -2) minimum
Step-by-step explanation: since the graph is going upwards and the arch of the graph is the lowest point in the graph, it will be a minimum point. to find this minimum point, look at what point the lowest point of the graph (for this graph, it is (-2, -2) )
System of equations:


The intersection point for this is <em>(4,11)</em>.
y = mx , where m is a slope,
m= rise/run
We have y = 15x, so m =15 and rise/run =15, then
rise = 15, run = 1
Answer:

Step-by-step explanation:
If you have the same denominator, you can just subtract the numerators normally and carry over the denominator.
