Y-3=1/2 (x+4) in standard form

the domain represents all the x values and range represents all the y value

In a function y=mx+b ( linear equation), the problem is giving the y values so plug in the value of each (y) in the equation to get x.

example: the range is : { 2,4,6} find the domain in the function y=x+1

y=x+1  take value 2

2=x+1

this goes for linear equation
