Can you answer my questions please? I'll fan/medal ;-;

OpenStudy (epoweritheta):

ya tel me

OpenStudy (anonymous):

Okay wait.. \[2x-3y=9\] A. Positive B. Negative \[y=-4x+5\] A. Positive B. Negative x |y --- −1 |−5 --- 1 |1 --- 3| 7 A. Positive B.Negative x |y --- 1 |−2 --- 2| −6 --- 3 |−10 A. positive B.Negative

OpenStudy (anonymous):

Ugh wait.

OpenStudy (anonymous):

3 and four are glitching

OpenStudy (epoweritheta):

what is this ??? i cant understand the question correctly , take a screen shot and send me

OpenStudy (anonymous):

Here it is

OpenStudy (anonymous):

OpenStudy (epoweritheta):

write 1st equation in the form , y=mx+c

OpenStudy (anonymous):

okay wouldn't that be \[3y=2x-9\]

OpenStudy (epoweritheta):

ya divide both sides by 3 , and tell the equation so the equation is the form \[y=mx+c\] , where m is the slope and c is the y intercept

OpenStudy (anonymous):

\[y=2x-3?\]

OpenStudy (epoweritheta):

no \[y = \frac{ 2 }{ 3 }x+3\]

OpenStudy (anonymous):

I was close =-=

OpenStudy (anonymous):

so wait..\[y=\left(\begin{matrix}2 \\ 3\end{matrix}\right)x=3\]

OpenStudy (epoweritheta):

what ??????

OpenStudy (anonymous):

\[y=\left(\begin{matrix}2 \\ 3\end{matrix}\right)*3 + 3*3= y=9????\]

OpenStudy (anonymous):

y=6x+9

OpenStudy (epoweritheta):

what is y=6x+9 ??????????????????????????????????????????????????????????????

OpenStudy (anonymous):

0-0' bruh arent you helping?

OpenStudy (anonymous):

Column B A. positive B. negative

OpenStudy (anonymous):

Rate of change is also known as slope

OpenStudy (anonymous):

2x – 3y = 9 To find the slope of this, change it into slope-intercept form(y = mx + b): 2x - 3y = 9 Subtract 2x to both sides: -3y = -2x + 9 Divide -3 to both sides: y = 2/3x + 3 Now it's in the form of y = mx + b, where m = slope. So here the slope or average rate of change is POSITIVE 2/3.

OpenStudy (anonymous):

Yep, and that's positive. So so far we have: 1 - Positive 2 - Negative 3 - Positive Now we do the same thing with #4: Let's take (2, -6) and (3, -10): m=y2−y1x2−x1 m=−10+63−2 Add & Subtract: m=−41 Can you divide that

Jeez thanks random nice lady 0-0

OpenStudy (anonymous):

ur wel

OpenStudy (anonymous):

Need Any more help

OpenStudy (anonymous):

ya sadly that was question 1 :|

OpenStudy (anonymous):

K i lov helpin people

OpenStudy (anonymous):

brb
