Advocard [28]

Answer:

$y=-\frac{2}{5} -1$

Step-by-step explanation:

So first thing is that slope intercept form is setup like this

y=mx+b

m=slope

b=y intercept

the slope is change in y over change in x

as y goes down 2 x goes up 5

so the slope is -2/5

the y intercept is at (0,-1) so the y intercept is -1

therefore the answer is

$y=-\frac{2}{5} -1$

have a great day :)

What seems to cause an Input value to be circled?

RideAnS [48]

Answer:

For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.

Step-by-step explanation:

For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.

For x $\leq$ 6, it would have a closed circle and you ARE including the 6 that is inputted.
