Hi

  • First to answer this question you must use the formula which is y = -3x+8
  • So as you can see the x is in the left ( -1,0,1,2) while the y we must find.
  • This is the explanation

  • As you can see the formula y= -3x+8
  • Based on the formula just replace the x to the value x given which is ( -1,0,1,2)

last repeat the way to find y. Use a scientific calculator to count easier ☺️

Explanation:

oh ? now that is really very simple. you take the value of x, put it into the equation, calculate the resulting y value, and put that y value into your table.

y = -3x + 8

x = -1

y = -3×-1 +8 = 3 + 8 = 11

x = 0

y = -3×0 + 8 = 8

x = 1

y = -3×1 + 8 = -3 + 8 = 5

x = 2

y = -3×2 + 8 = -6 + 8 = 2

you see how easy, simple and straight forward that is ? that is in fact how functions work.
