Please Explain it- Math

It is a horizontal line. The slope = 0.

The line cuts the y-axis at the point  

(0,9)

Step-by-step explanation:

y=9

is the equation of a horizontal line. The slope is 0.

If we write it in slope-intercept form we will have:

y=0x+9

This means that for any value of  x

that is chosen, the y-value is always 9 Hence  y

x=9.

The y-intercept is at the point  

(0,9)

answer: 0.64

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
