Question 121214
First find the slope of each of the two lines by rewriting the equatins in slope-intercept form: {{{y = mx+b}}}.
L1: {{{y = -(1/2)x+2}}}
L2: {{{y = -(1/2)x+5/4}}}
Now compare with:
{{{y = mx+b}}} and you can see that in both equations, {{{m = -(1/2)}}}
The slopes, m, are equal so the lines are parallel.
