Answer: 5 units</h3>
Work Shown:

I used the distance formula. Alternatively, you can plot the two points and form a right triangle. Then use the pythagorean theorem. The distance formula is effectively a modified version of the pythagorean theorem.
Answer:
-3/8 > -1 indicates that -3/8 is to the right of -1 in the number line.
Step-by-step explanation:
So it cuts the y axis at -9 as it has a gradient of 0.
Therefore y=-9 is the equation, as y=mx+c, it intercepts at -9 and has a gradient of 0, therefore y=0x-9 so y=-9.
