Answer:
y + 5 = -2(x - 7)
Step-by-step explanation:
The slope of the line y = (1/2)x + 4 is 1/2. Any line perpendicular to this one will have a slope which is the negative reciprocal of 1/2: -2.
Using the point-slope form, the desired equation is:
y + 5 = -2(x - 7)
The inequality says that the sum of the two numbers is zero or more.
Find one of the pairs where the sum of the two numbers is zero or more,
and that will be the one you're looking for.
