Which equation represents a line that passes through (–9,  –3) and has a slope of –6?
y  – 9 =  –6(x  – 3)
y  + 9 =  –6(x  + 3)
y  – 3 =  –6(x  – 9)
y  + 3 =  –6(x  + 9)

The answer is:

The last equation,

To find which of the given equations represents a line that passes through the point (-9,-3) and has a slope of -6, we need to find an equation that can be satisfied by evaluating the given point.

We can see that the only equation that can be satisfied evaluating the point (-9,-3) is the last equation:

Evaluating the point, we have:

We can see that the equation is satisfied!

Also, we can see that evaluating the point into the other equations, they will not be satisfied.

Let's prove that:

Evaluating:

First equation:

The equation is not satisfied.

Second equation:

The equation is not satisfied.

Third equation:

The equation is not satisfied.

Hence, the correct option is the last option, the equation that represents a line that passes through (–9, –3) and has a slope of –6 is the last equation:

Have a nice day!

Note: I have attached a picture for better understanding.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
