Answer:
y = 4x
Step-by-step explanation:
We need to look at where the line's dots are to find the slope. Between each dot the line goes 1 to the right and 4 up. Remember the saying rise over run to know that the slop is 4/1. 4/1 is just 4 so in the equation we put that next to x.
The next part of making an equation is the y-intercept, or where it crosses the y-axis. Since this hits the y-axis at 0 the complete equation will be
y = 4x + 0
but obviously we don't need to add 0 so the answer is
y = 4x
A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
