How do I solve this linear equation ?
Which of the following ordered pairs are a solution to the equation y=-x+1
(-1,4)
(3,-2)
(-5,6)
(-6,4)
Which of the following ordered pairs are a solution to the equation y=-x+1
(-1,4)
(3,-2)
(-5,6)
(-6,4)
?
// You can actually substitute each point for x and y
// in the equation and see which point generates a
// true statement
(-1,4): y=-x+1 ⇒ 4 ≠ -(-1)+ 1
(3,-2): y=-x+1 ⇒ -2 = -3 + 1............TRUE
(-5,6): y=-x+1 ⇒ 6 = -(-5) + 1..........TRUE
(-6,4): y=-x+1 ⇒ 4 ≠ -(-6) + 1
