Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
  = 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
   = 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
   = 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8 
Plugin x = 20 in the equation
y = 20 - 7
y = 13
