Hi! Your answer is y = x + 4
Please see an explanation for a better and clear understanding to your problem!
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Here are the reasons why it's A choice which is y = x + 4.
- The graph passes through y-axis at (0,4) which makes it obvious that the graph has y-intercept/b-value equal 4.
- The graph has slope of 1. We can tell by rise over run (A glance can tell that the graph has slope of 1.)
- Other choices have y-intercept at (0,0) also known as "origin point". The graph shown doesn't pass an origin point but passes through (0,4) as explained.
Here is the slope-intercept form, it might benefit you in some questions!
where m = slope and b = y-intercept.
Hope this helps! :)
