Answer:
y = 1/2 x + 8
Step-by-step explanation:
We are given the y intercept and the slope, so we can write the equation using the slope intercept form
y = mx+b where m is the slope and b is the y intercept

21-20 = 1
20-18 =2
18 -15 = 3
15-11 = 4
We are subtracting 1 more each time
11-5 = 6
y=3/4. ×=-3/2
y-3/4=0
×+3/2=0
y-3/4=x+3/2
y=x+3/2+3/4
y=(2x+6+3)/4
4y=2x+9
4y-2x-9=0
