Question 1080807


the {{{slope}}} of the line {{{parallel}}} to line {{{x + 2y = 5}}} is same as the {{{slope}}} of this line

so, find the {{{slope}}} of {{{x + 2y = 5}}}:

{{{ 2y = -x+5}}}

{{{ y = -x/2+5/2}}}

{{{ y = -(1/2)x+5/2}}}=> the {{{slope}}} is {{{highlight(m=-1/2)}}} and {{{parallel}}} line have same slope
