Question

1. Write by inspection the slope of each (a) 2x - y = 5

Answer 1

We have the following:

$2x-y=5$

now, in the slope and intercept form of the equation the line is the following

$y=mx+b$

where m is the slope, that is, we have to solve for and, therefore we solve for and in the line (a) and we are left

$\begin{gathered} 2x-y=5 \\ (-1)\cdot(-y)=(-2x+5)\cdot(-1) \\ y=2x-5 \\ m=2 \end{gathered}$

Therefore, the slope is 2
