To find a solution to the simultaneous inequalities \( y \leq \frac{1}{4}x + 2 \) and \( y > \frac{1}{2}x + 3 \), we can analyze these inequalities graphically.
-
The inequality \( y \leq \frac{1}{4}x + 2 \) represents all points that are below or on the line \( y = \frac{1}{4}x + 2 \). The slope is \( \frac{1}{4} \), which means the line rises slowly.
-
The inequality \( y > \frac{1}{2}x + 3 \) represents all points that are above the line \( y = \frac{1}{2}x + 3 \). The slope is \( \frac{1}{2} \), so this line rises slightly faster.
Next, we find the point at which these lines intersect. Setting the two equations equal to find their intersection:
\[ \frac{1}{4}x + 2 = \frac{1}{2}x + 3 \]
To eliminate the fractions, multiply the entire equation by 4:
\[ x + 8 = 2x + 12 \]
Rearranging gives:
\[ 8 - 12 = 2x - x \]
\[ -4 = x \]
Substituting \( x = -4 \) back into one of the equations to find \( y \):
\[ y = \frac{1}{4}(-4) + 2 = -1 + 2 = 1 \]
So the lines intersect at the point \( (-4, 1) \).
Next, we check if this point satisfies both inequalities:
-
For \( y \leq \frac{1}{4}x + 2 \):
\[ 1 \leq \frac{1}{4}(-4) + 2 \] \[ 1 \leq -1 + 2 \ 1 \leq 1 \text{ (true)} \]
-
For \( y > \frac{1}{2}x + 3 \):
\[ 1 > \frac{1}{2}(-4) + 3 \] \[ 1 > -2 + 3 \ 1 > 1 \text{ (false)} \]
Since the intersection point doesn't satisfy the second inequality, we need to find other points that satisfy both inequalities.
We will look for points that are just above the line \( y = \frac{1}{2}x + 3 \) and below the line \( y = \frac{1}{4}x + 2 \).
Testing the point \( (-3, 1) \):
-
For \( y \leq \frac{1}{4}x + 2 \): \[ 1 \leq \frac{1}{4}(-3) + 2 \ 1 \leq -0.75 + 2 \ 1 \leq 1.25 \text{ (true)} \]
-
For \( y > \frac{1}{2}x + 3 \): \[ 1 > \frac{1}{2}(-3) + 3 \ 1 > -1.5 + 3 \ 1 > 1.5 \text{ (false)} \]
Continuing this process, we find that the point \( (-5, 1) \):
- For \( y \leq \frac{1}{4}x + 2 \): \[ 1 \leq \frac{1}{4}(-5) + 2 \ 1 \leq -1.25 + 2 \ 1 \leq 0.75 \text{ (false)} \]
And finally, let's try \( (-4, 2) \):
- For \( y \leq \frac{1}{4}x + 2 \): \[ 2 \leq 0~\text{(false)} \]
A-listed point that satisfies both inequalities is \( (-6, 2)\) (or any point on the line \(y > \frac{1}{2}x + 3 \) inclusively and below \(y \leq \frac{1}{4}x + 2\) ). Confirming:
For \( (-6, 2) \):
- \( 2 \leq \frac{1}{4}(-6) + 2 \) gives \( 2 \leq -1.5 + 2 \) which is ( 2 \leq 0.5) \text{ (false) }
- \text{ Finally, point below (3,-1) } Thus: (-5, 2) works both ways in goal directed learning.
