@Will.H

OpenStudy (mjazzw7):

second one because 2, 8 has a point. please fan and medal thanks :)

Use the two point that lie on the line. `(0,8) and (6,5)` Find the slope. You are already given the y-intercept as being `8`.

563blackghost (563blackghost):

\(\LARGE\bf{\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \rightarrow \frac{5-8}{6-0}}\)

@Will.H

OpenStudy (will.h):

Take 2 points to find the slope And the y intercept is when x = 0 (0,8)(6,5) Slope = Y2-Y1/X2-X1 Slope = 5-8/6-0 Slope = -3/6 Slope = -1/2 And the y intercept is 8 Thus The equation is Y = (-1/2)x + 8

OpenStudy (volleyballlover55):

ok next! http://prntscr.com/djgfo8

OpenStudy (will.h):

Also ghosty gave a good explanation

OpenStudy (will.h):

I have to go tho. Ghost will help xD.

563blackghost (563blackghost):

Thank you William ;) Yours is too :)

OpenStudy (volleyballlover55):

ok!!!!!! :) http://prntscr.com/djgfo8

563blackghost (563blackghost):

Identify the two points that lie on the line and find the slope. We see that the y-intercept is already told showing that it is `10`. `(1,9) and (6,4)` We find the slope. \(\LARGE\bf{\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \rightarrow \frac{4-9}{6-1}}\) What is the slope?

OpenStudy (volleyballlover55):

-5/5?

563blackghost (563blackghost):

Correct ;) Though we simplify it to be `-1`. So the slope-intercept is. \(\LARGE\bf{y=-x+10}\) Now we would input the cups of coffee `(9)` into the function as `x`. \(\LARGE\bf{y=-(9)+10}\)

OpenStudy (volleyballlover55):

so c?

OpenStudy (volleyballlover55):

@563blackghost ??? @Will.H ??

563blackghost (563blackghost):

Not quite. \(\LARGE\bf{y=10+-9}\) It could not be `9`. Try again :)

OpenStudy (will.h):

What's the result of -9 + 10

OpenStudy (volleyballlover55):

1?

OpenStudy (will.h):

Yeah

563blackghost (563blackghost):

Nice :)

OpenStudy (volleyballlover55):

so A?

OpenStudy (volleyballlover55):

@563blackghost

563blackghost (563blackghost):

Yes ma'am.

OpenStudy (volleyballlover55):

ok do you want me to make a new thread to start fresh?? i have lotsss of questions

563blackghost (563blackghost):

Im sorry but I have to take my leave for the afternoon, good luck with your work ;)
