Which of the following are arithmetic sequences? a. 9, 6, 3, 0
b. 8, 9, 11, 14, 18, . . .
c. 50, 52, 54, 56, . . .
d. –3, –5, –9, –11, –15, –17, . . .
e. 7, 21, 35, 49, . . .

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

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
