Question

write a rule for the function of input(x) is 0,4,8,12 and output(y) is 5,7,9,11

Answer 1

a rule like an equation?

Answer 2

y= 3/5x + 5

Answer 3

y=1/2x+5

Answer 4

Dee is correct,

for every increase of 4 in the x's the y's increase by 2
so slope = 2/4 = 1/2
so y = (1/2)x + b
but (0,5) is the y-intercept, so b=5

y = (1/2)x + 5
