Please help I gave extra points please it’s super simple to some of you I just don’t know how to do it :(

Answer:1. The required slope m, for the context is[tex]m = \frac{-25}{3}[/tex]2. The y-intercept in the context is [tex]P_{2}(d) = y = 100[/tex]3. The x-intercept of the linear model is [tex]d = x = 12[/tex]Step-by-step explanation:Given:[tex]P_{2}(d) = \frac{-25}{3}\times d + 100[/tex]Where, [tex]P_{2}[/tex] is the number of phones.d is the number of days he has worked that week.This is a linear model type equation.Can be represented in the slope intercept form  which is equal to[tex]y = mx + c[/tex]Where,m = Slope of the line.c = y-intercept.Now if we compare the given model by slope intercept formula we get[tex]m = \frac{-25}{3}\\\\c = 100[/tex]So ,the slope in the context of the problem is [tex]m = \frac{-25}{3}[/tex].and the y intercept in the context of the problem [tex]P_{2}(d) = c = y = 100[/tex]For finding x-intercept put y = 0Here,[tex]P_{2}(d) = 0[/tex][tex]\therefore 0 = \frac{-25}{3}\times d + 100\\ \therefore \frac{25}{3}\times d = 100\\\therefore d=\frac{300}{25}\\\therefore d=12[/tex]So, the x intercept of the linear model is [tex]d = x = 12[/tex]
