On a number line, the distance from zero to -7 is 7 units. which equation demonstrates this concept? a. |-7| = 7 b. |-7| = -7 c. 72 = 49 d. 0 + 7 = 7

Option A. |-7| = 7

Solution:

The distance is a positive value, then we must not take in account the sign, and using:

|a| =-a if a<0

with a=-7

|-7| = -(-7)

|-7| = 7

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer: it is d
