Question 575594
in the formula for slope intercept form is the easiest way for me to find the slope of an equation
{{{y=mx+b}}} where {{{m}}}= slope
so:
1) was 1 suppose to be {{{y=2x+1}}}, or {{{y=2x-1, or y=2x=1
well if you meant one of the first two then the m=2 or the slope is equal to 2/1. if you meant y=2x=1 then y=1 and there is no slope so the slope is 0.
.
2) {{{2x-6y=8}}} subtract 2x
{{{-6y=8-2x}}} divide by -6
{{{y=(8-2x)/-6}}} divide each by -6
{{{y=((8)/-6)+((-2x)/-6)}}} reduce and check signs
{{{y=-4/3+x/3}}} communitive proporty of addition
{{{y=x/3-4/3}}} identify the slope
{{{y=(1/3)x-4/3}}}
{{{m=1/3}}}
slope is {{{1/3}}}
.
3){{{4-y=0}}}
{{{4=y}}}
{{{m=0}}} no slope
.
4){{{2y=-x}}}
{{{y=-x/2}}}
{{{y=(-1/2)x}}}
{{{m=-1/2}}} slope is {{{-1/2}}}
