Answer:

  • 13

Step-by-step explanation:

Put input value instead of the x into equation and calculate the output:

  • y = -5x - 7

x = -4, then find the value of y:

  • y = -5(-4) - 7 = 20 - 7 = 13

The output is 13 when the input is -4

[tex]\\ \rm\longmapsto y=-5x-7[/tex]

[tex]\\ \rm\longmapsto y(-4)[/tex]

[tex]\\ \rm\longmapsto -5(-4)-7[/tex]

[tex]\\ \rm\longmapsto 20-7[/tex]

[tex]\\ \rm\longmapsto 13[/tex]
