Question

10 - 6 = 4
x | y = 6 - 0,8x
-8 |
-9 |
-10 |
-11 |
-12 |

Explanation:

Step1: Substitute x=-8 into formula

$y = 6 - 0.8\times(-8) = 6 + 6.4 = 12.4$

Step2: Substitute x=-9 into formula

$y = 6 - 0.8\times(-9) = 6 + 7.2 = 13.2$

Step3: Substitute x=-10 into formula

$y = 6 - 0.8\times(-10) = 6 + 8 = 14$

Step4: Substitute x=-11 into formula

$y = 6 - 0.8\times(-11) = 6 + 8.8 = 14.8$

Step5: Substitute x=-12 into formula

$y = 6 - 0.8\times(-12) = 6 + 9.6 = 15.6$

Answer:

$x$	$y=6-0,8x$
-9	13.2
-10	14
-11	14.8
-12	15.6
