Which equation is represented by the line

gulaghasi [49]

Answer:

First, we need to find the slope of this line.

Slope is defined as rise over run, or change in y over change in x. We find two points on this line, and see that the slope is -4.

Then, we find the y-intercept, which in this case is 0.

Using slope intercept form, our answer is y=-4x

Let me know if this helps!

Please help Cant figure it out

IrinaVladis [17]

Answer:

Step-by-step explanation:

If a number is to the power of a negative number, then it is just that number's reciprocal: e.g. y⁻ˣ = $\frac{1}{y^{x} }$

Therefore, m⁻² will be m² in the denominator, as n⁻³ will be n³ in the numerator.

That will look like $\frac{3n^{3} }{5m^{2} }$ .

So, that is C.

$\huge\boxed{\text{Dominic}}$

In this problem, $0$ represents the sea level. Since Dominic is $175$ feet below the surface (sea level), his current location is at $-175$ feet.

The same concept can be applied to Karen, who is at $-138$ feet.

We need to find who is lower, or farther below $0$ . This means the answer is $\boxed{\text{Dominic}}$ .
