@dude @mhchen

dude:

Look at the y-intercept first, where is the y-intercept in this graph?

Nicole:

is it 7?

dude:

Not quite, y-intercept is when the graph touches the y-axis zPsrNKNxTGqO6CdHSE7o1w.png

Nicole:

-1

dude:

Right, which have -1 as the y-intercept in the answer choices?

Nicole:

C

dude:

Both C and D have it, its not C though C says that y is less than The shaded area is above the line so it should be D

Nicole:

https://prnt.sc/lc1k44 last one^

dude:

Again, look for the y-intercept From there look at whether the shaded area is above or below the line

Nicole:

-3

Nicole:

above

dude:

Right, so which has -3 as the y-intercept and shows that y is greater? Note: it can be written as: \(y\ge number\) or \(number\le y\)

Nicole:

C or D?

dude:

Yes

Nicole:

Which one do u think

dude:

D \(y\ge \frac35x-3\) The sign opens towards the y, meaning that y is greater

Nicole:

Okay bet thank you

dude:
