Find the contact of proportionality (r) in the equation y=rx

If it's proportional, then to find the constant just divide the y - value by the x - value.

Take the first point, (5.8, 5.8).

Divide 5.8 by 5.8 to get your constant of proportionality: r = 1.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
