Answer:
The correct answer is d) the ratio of the change in y to the change in x along the line.
We can tell this by looking at the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
Answer:
The two numbers are 13 and 6.
Step-by-step explanation:
x+y=19
x-y=7
-----------
2x=26
x=26/2
x=13
13+y=19
y=19-13
y=6
x=13, y=6.
