Question

Consider this linear function:
y=1/2x+1

Plot all ordered pairs for the values in the domain.

D: {-8, -4, 0, 2, 6}

Answer 1

the domain is the set of x-values in the function

so, you'd need to find the corresponding y-value for each x-value, then plot the (x,y) values

let's start with the first value, x = -8

plug this into the function

y=1/2x+1

y= (1/2)(-8) + 1
= -4 + 1 = -3

so you'd plot (-8,-3) as your first point

repeat with the rest of the domain values
