- Hey mom i'm having some issues with this math problem. the problem is y=1/2x+9 and y=-x+6
- sure I would love to help!
- Oh my favorite system of equations. We can use the method of substitution, elimination, or graphing. Let first put this into real world terms so you can understand
- Mary is going swinging she goes ½ a mile down from the underwater starting point to reach the target then swam 9 feet down to hit the next marker. Rob went up for air so he went up 1 mile and then swam 6 feet down to reach the first marker. How long where the under for. Does this make it easier to understand?
- Definitely! While you were explaining I went through my notes and chose to solve with graphing
- Cool! Make sure its in y=mx+b. for the first problem ½ is m and b is 9. For the second m=-1 and b=6. Then graph m and b.
- That’s helped so much.
- You can also use desmos. You enter each equation in a separate block and click where they intercept. Where they intercept its your answer
- I didn’t know you could do that.
- No problem! Let me know if you want to learn the other methods!
- I got it! Its (-2,8) thank you for helping me
