Can someone teach me how to do these problems, please?
Determine whether A, B, and C lie on the same line (without graphing). Given A(2,2), B(-2,-6), C(6,10) Solve for N 2 n+1 = 8 { the n+1 is the exponents of 2. } PLEAASE HELP THIS WILL DO SO MUCH FOR MY GRADE. Haha. |

For the first one: You calculate the slope (Δy/Δx) between each point (between A and B, B and C and A and C). If the slope is the same, then they are all on the same line.
For 2^(n+1)=8: You know that 2^3 is 8, so you replace that for 8, thus getting 2^(n+1)=2^3. Then, because they have the same base, the powers should equal each other: n+1 = 3. You then get that n=2. |
