What is the first step to solving a system of linear equations algebraically?
I attached a graph of the function. You could use the slope-intercept form to easily hand draw it, or of course you could graph it yourself with a graphing calculator.
The domain of a graph refers to x-values. Basically, for how many x values will you have a real value? The range of a graph refers to y-values. Just as a tip, you don't even need a graph to know that an equation in this format generally has a domain and range of all real numbers.
About Reciprocal:
It's when a fraction is flipped.
Example:
- 2/3..... The reciprocal for 2/3 is 3/2.
- 3/5.... The reciprocal for 3/5 is 5/3.
