Ta có : \(y=5x-1\)
\(\Rightarrow y=5.\left(-5\right)-1=-26\)
\(y=5.\left(-4\right)-1=-21\)
\(y=5.\left(-3\right)-1=-16\)
\(y=5.\left(-2\right)-1=-11\)
\(y=5.\left(0\right)-1=-1\)
\(y=5.\left(15\right)-1=74\)
y = 5x - 1
y = 5. (-5) - 1 = -26
y = 5. (-4) - 1 = -21
y = 5. (-3) - 1 = -16
y = 5. (-2) - 1 = -11
y = 5. 0 - 1 = -1
y = 5.15 - 1 = 74
