Chose an equation below that represents the line passing through the point (-2,-3) with a slope of -6
olganol [36]
Hey there!

Let's take a look at this problem... Okay so for these questions there is formula known as the point-slope formula that is used...

(y - y₁) = m(x - x₁)

From here on out you substitute in your given values...

(y + 3) = -6(x + 2)
y + 3 = -6x -12
<u>y = -6x -15</u><u />                <----- That's your answer! 

I hope this helped you!

Consider the functions. F(x)=(x+1)2-4 and g(x)=-4|x+1| which statement compares the range of the functions?
Andreyy89

Answer:

<h2>        The fourth</h2>

Step-by-step explanation:

Vertex of f is (-1, -4) so its range is limited to y≥-4

|x+1| is always ≥0 therefore -|x+1| is always ≤0 {4 is insignificant to this - slope doesn't mean in range} so its range is limited to y≤0
