Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Slope is change in y over change in x, or (y2 - y1) / (x2 - x1). Pick two points, and the change in the y-coordinates over the change in x-coordinates is the slope.
Answer:
y
Step-by-step explanation:
8 nickels = 40 cents
y < 8
x < 35
Let's test
1 nickel and 35 pennies. That doesn't work
4 nickel and 20 pennies. That works. Perhaps we be more precise?
5 nickels and 15 pennies. Right on the point. 20 coins.
Hope this helps :)
Have a nice day!
