Answer: (-6, 32) and (4,-18)
Step-by-step 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.
Answer:
Choice C and D are the answer.
Step-by-step 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.
