What are the determinants for solving this linear system?<br> 5x + 3y = 17<br> −8x − 3y = 9

Ksivusya [100]

For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9

Find the slope of the line that passes through (-1,6) and (15,6)

svp [43]

Slope = $\frac{Y2 - Y1}{X2 - X1}$
------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line
