Determine the slope of the line x + 2y -3 = 0 .

Expert Answers

An illustration of the letter 'A' in a speech bubbles

 The slope in the standard formula :

y=mx +b

The slope =m

We have the equation :

x+2y-3=0

we need to rewrite it in the standard formula:

2y= -x+3

==> y= (-1/2)x +3/2

Then the slope = -1/2
