Pumping iron: 10x+90=0
Fit for life: 15x+50=0
Set them equal to each other. 10x+90=15x+50. Solve for x. Subtract 50 from both sides, get 10x+40=15x, then subtract 10x from both sides, getting 40=5x. Divide 5 from both sides to isolate x, x=8. After 8 months the two gyms will cost the same.

Answer:
![y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%204%5Bx%20-%201%5D%5C%3Aor%5C%3Ay%20%2B%202%20%3D%204%5Bx%20-%202%5D)
Step-by-step explanation:
First find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:


Then plug each of these coordinates into the Point-Slope Formula,
Now remember, in this formula, all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS:
![y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%204%5Bx%20-%201%5D%5C%3Aor%5C%3Ay%20%2B%202%20%3D%204%5Bx%20-%202%5D)
