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! :)
For each of the given answer choices, substitute the x-value into the given equation f(x) = 3(1/4)^x and see the equation gives the same f(x), or y-value.
Remember f(x) is the same thing as y and so coordinates for a point are in problem is (x, f(x))
Let's try the first coordinate (-2, 48). The x-value given by the coordinate is -2 and the f(x) value is 48.
Substituting x as -2
into the equation,
This matches with the answer choice (-2, 48) so A should be correct.
But you can also check the other answer using the same process to make sure.
