Hey so I have a math test tomorrow and I'm really good in math, I just need some small clarification, so here's my problem. V(-2,k) P(4,9) slope of 2/3 so I decided to find y=mx+b with P(4,9) because after I find B I could do the same with V(-2,k) so I did the equation and B came up 7, so next I decided to do. y=2/3(-2)+7 but I got, y=17/3 However in the optional choice there's only -5, 3, 5 and 7 I asked my friend and he said it was 5 but I didn't really understand his explanation so I would really appreciate some deeper or simple explanation please, my friend also told me that the way I was doing it wouldn't work and I was just wondering as to why not ? thank you for your time. ps: It may not be called a slope but I come from a french school and that was the translation I came up with.
