Best ResponseYou've already chosen the best response.1First, find the slope: \(\sf \color{blue}{slope} = m =\color{red}{\frac{y_2y_1}{x_2x_1}}\) it is also the change in points Once you have that, plug it into your pointslope formula: \(\sf \color{orange}{yy_1=m(xx_1)}\) where you can pick \(any\) of the two points you have. they will give you the SAME answer.

Best ResponseYou've already chosen the best response.1You can leave it as is, or change it to a line, which is in the form: \(\sf \color{green}{y=mx+b}\)

Best ResponseYou've already chosen the best response.0I got y+1=mx7. Is that right?

Best ResponseYou've already chosen the best response.1No. It's incorrect. Your first step is to find the slope. What is your slope?

Best ResponseYou've already chosen the best response.1I see what you did wrong, but you picked the wrong points, I think you used your slope as your points. But your slope is just your slope. \(\sf \color{red}{m}\) is your slope. And it can be a fraction. It simply means rise over run: \(\sf \color{orange}{\frac{rise}{run}}\)

Best ResponseYou've already chosen the best response.1Yes, correct. That's your slope. Now, plug it into: \(\sf \color{orange}{yy_1=m(xx_1)}\)

Best ResponseYou've already chosen the best response.1for y\(_1\) and \(\sf x_1\) pick \(\sf \color{red}{one}\) of the two points you have. It can be either E or F

Best ResponseYou've already chosen the best response.0\[y=\frac{ 1 }{ 7 }x\] is this right?

Best ResponseYou've already chosen the best response.1So you have: \(\sf \color{green}{y1=\frac{1}{7}(x5)}\) Can you solve it now, using algebra, to rearrange it into the form: \(\sf \color{red}{y=mx+b}\)

Best ResponseYou've already chosen the best response.0\[y=\frac{ 1 }{ 7 }+4\] I think I got it this time
