Please help I will mark brainliest
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

Yes they form a proportion the rate of change is 27.5
4*27.5=110
10*27.5=275
