Question

fill in the table using this function rule.
y = -5x - 2

xy
-1
0
1
2

Explanation:

Step1: 代入x=-1计算y

将\( x = -1 \)代入\( y = -5x - 2 \),得\( y = -5\times(-1) - 2 = 5 - 2 = 3 \)。

Step2: 代入x=0计算y

将\( x = 0 \)代入\( y = -5x - 2 \),得\( y = -5\times0 - 2 = 0 - 2 = -2 \)。

Step3: 代入x=1计算y

将\( x = 1 \)代入\( y = -5x - 2 \),得\( y = -5\times1 - 2 = -5 - 2 = -7 \)。

Step4: 代入x=2计算y

将\( x = 2 \)代入\( y = -5x - 2 \),得\( y = -5\times2 - 2 = -10 - 2 = -12 \)。

Answer:

xy
0-2
1-7
2-12
