Create a positive graph linear and calculate the rate of change

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
