Chapter 11: Q. 28 (page 773)

Graph each equation of the system. Then solve the system to find the points of intersection.
$\{\begin{cases} x^{2} - 4 y^{2} = 16 \\ 2 y - x = 2 \end{cases}$

Short Answer

Expert verified

The point of intersection is $(- 5, - \frac{3}{2})$ .

Step by step solution

Step 1. Given information

$\{\begin{cases} x^{2} - 4 y^{2} = 16 \\ 2 y - x = 2 \end{cases}$

Step 2. Graphing each equation

$x^{2} - 4 y^{2} = 16$

$2 y - x = 2$

Step 3. Calculation of intersection point

$C o n s i d e r, x^{2} - 4 y^{2} = 16 . . . . . (1) 2 y - x = 2 . . . . .
