Answer 1

m = 2

Explanation:

The given equation is :

8x – 4y - 9 = 0

The general equation of a line is given by :

y = mx+b ...(1)

here m is slope and b is y-intercept

Equation (1) can be written as :

8x – 4y = 9

Dividing both sides by (-4)

`(8x)/(-4)-(4y)/(-4)=(9)/(-4)\\\\-2x+y=-(9)/(4)\\\\y=2x+(-9)/(4)` ...(2)

Comparing equation (1) and (2), we get :

m = 2

Hence, the slope of the line is 2.
