Hi there!

Use slope formula to solve for the slope of the line:

Plug in points into the equation. We can use the points (0, -10) and (25, -5):

Answer:
20 cm
Step-by-step explanation:

1. Multiply the actual depth my the scale factor of 1/15.
2. Multiply the resulting depth after multiply by the scale factor by the conversion factor of meters to centimeters.
Answer:
A
Step-by-step explanation:
The solution to a system of equations is the point of intersection of the 2 lines.
The lines intersect at (6, 9 ) ← solution
Answer:
1:3
Step-by-step explanation:
Both numbers are divisible by 25:
∴ The simplified ratio is 1:3
Hope this helps!
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
