In which quadrants do solutions for the inequality y ≤ 2/7x +1 exist?
viktelen [127]

All four quadrants

<h2>Explanation:</h2>

We have the following inequality:

y \leq \frac{2}{7}x+1

So the first step we need to perform is to plot the line:

y = \frac{2}{7}x+1

If \ x=0 \\ \\ y=\frac{2}{7}(0)+1 \\ \\ y=1 \\ \\ \\ If \ y=0: \\ \\ 0=\frac{2}{7}(x)+1 \\ \\ x=-\frac{7}{2}=-3.5

So the line passes through the points:

(0,1) \ and \ (-3.5,0)

To find the shaded region, let us take a point, namely, the origin and test it in the inequality:

y \leq \frac{2}{7}x+1 \\ \\ 0\leq \frac{2}{7}(0)+1 \\ \\ 0\leq 1 \ True!

Since this is true, then the shaded region includes this point. This is shown below and <em>as you can see the solutions exist in all four quadrants.</em>
