2y+8x=21
This is in standard form, lets convert to slope intercept form

slope intercept form : y = mx + b

2y + 8x = 21
-8x -8x

2y = -8x + 21
y = -4x + 21/2

Answer: m = -4

8x + 2y = 21
8x - 8x + 2y = -8x + 21
2y = -8x + 21
2 2
y = -4x + 10.5

Slope: -4

Answer:

Third option is the right choice.

Step-by-step explanation:

Manipulate the right hand side.

$\sec \left(x\right)\\\\=\frac{1}{\cos \left(x\right)}\\\\\mathrm{Use\:the\:following\:identity}:\quad \:1=\cos ^2\left(x\right)+\sin ^2\left(x\right)\\\\=\frac{\cos ^2\left(x\right)+\sin ^2\left(x\right)}{\cos \left(x\right)}\\\\\Rightarrow \mathrm{True}$
