Question

1. $y=\frac{1}{4}x+5$

$x$	0	4	8	12
$y$

Explanation:

Step1: Substitute $x=0$

$y=\frac{1}{4}(0)+5=0+5=5$

Step2: Substitute $x=4$

$y=\frac{1}{4}(4)+5=1+5=6$

Step3: Substitute $x=8$

$y=\frac{1}{4}(8)+5=2+5=7$

Step4: Substitute $x=12$

$y=\frac{1}{4}(12)+5=3+5=8$

Answer:

When $x=0$, $y=5$; when $x=4$, $y=6$; when $x=8$, $y=7$; when $x=12$, $y=8$

Filled table values for $y$: 5, 6, 7, 8
