Question

For each ordered pair determine whether it is a solution to y= -5x+2

(5, 49)

(-3, 28)

(-6, 32)

(4, -18)

Answer 1

Choice C and D are the answer.

Explanation:

We have given an expression.

y= -5x+2

We have to choose the ordered pair (x,y) which satisfies the given equation.

A. (5,49)

49 = -5(5)+2

49 = -25+2

49 = -23 (not true)

B.(-3, 28)

28 = -5(-3)+2

28 = 15+2

28 = 17 (not true)

C. (-6, 32)

32 = -5(-6)+2

32 = 30+2

32 = 32 true

D. (4, -18)

-18 = -5(4)+2

-18 = -20+2

-18 = -18 true

Hence,(4, -18) and (-6, 32) are the solutions of y = -5x+2.

Answer 2

Answer: (-6, 32) and (4,-18)

Explanation:

Here the given expression is,

y = - 5x + 2

If a order pair satisfies the equation it is called its solution.

For, (5, 49),

49 = -5 × 5 + 2 ( False )

For, (-3, 28),

28 = -5 × 3 + 2 ( False )

For (-6, 32)

32 = -5 × - 6 + 2 ( true )

For, (4, -18)

-18 = -5 × 4 + 2 (True )

Hence, only the order pairs (-6,32) and (4,-18) are satisfying the given equation,

⇒ (-6,32) and (4,-18) are the solution of the given equation.
