Answer:

a). y = 3/2x - 3/4 b).-2/3 c).y = -2/3x + 3

Step-by-step explanation:

a). 6x – 4y = 3

-4y = -6x + 3

y = 3/2x - 3/4

- The slope is 3/2.

b). The slope of a perpendicular line would be the opposite: -2/3

c). y = -2/3x + b

-1 = -2/3(6) + b

-1 = -4 + b

3 = b

y = -2/3x + 3

Mariana [72]

Answer:

$\sec \theta = -\frac{\sqrt{61}}{5}$

Step-by-step explanation:

The secant can be found by the following trigonometric relation:

$\sec \theta = \frac{1}{\cos \theta}$

$\sec \theta = \frac{1}{\frac{x}{r} }$

$\sec \theta = \frac{r}{x}$

$\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}$

$\sec \theta = \frac{\sqrt{(-5)^{2}+(-6)^{2}}}{(-5)}$

$\sec \theta = -\frac{\sqrt{61}}{5}$
