<span>It will take Yanni 20 minutes to catch up with Tracy. This can be determined with the fact that average velocity equals change in distance divided by change in time. Rearrange the equation so that we are solving for the final time, then set Tracy's equation equal to Yanni's equation and solve for the final time.</span>

Andreas93 [3]

is the same as picking from a points set hmmm, notice the table is an x,y table, so we can just pick any two points to get the slope and thereby the equation.


3)


let's use (100, 36.5) and (300, 106.5)


\bf (\stackrel{x_1}{100}~,~\stackrel{y_1}{36.5})\qquad  (\stackrel{x_2}{300}~,~\stackrel{y_2}{106.5}) \\\\\\ slope =  m\implies  \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{106.5-36.5}{300-100}\implies \cfrac{70}{200}\implies \cfrac{7}{20} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-36.5=\cfrac{7}{20}(x-100) \\\\\\ y-36.5=\cfrac{7}{20}x-35\implies y=\cfrac{7}{20}x+1.5


4)


and for this one let's pick say (35, 88) and (45, 82)


\bf (\stackrel{x_1}{35}~,~\stackrel{y_1}{88})\qquad  (\stackrel{x_2}{45}~,~\stackrel{y_2}{82}) \\\\\\ slope =  m\implies  \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{82-88}{45-35}\implies \cfrac{-6}{10}\implies -\cfrac{3}{5} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-88=-\cfrac{3}{5}(x-35) \\\\\\ y-88=-\cfrac{3}{5}x+21\implies y=-\cfrac{3}{8}x+109

The first choice does NOT represent a function

Step-by-step explanation:

the x vaules in the first two ordered pairs (2), each have a different y value which makes it nonfunctional :)
