Question 552296
<pre>

y = <font color="magenta">3</font>x + 5 

The slope is the coefficient of x, which is <font color="magenta">3</font> when the equation of the line is
solved for y.  It is positive so I colored it <font color="magenta">pink</font>

Here is the line:

{{{drawing(400,400,-10,10,-10,10, 

graph(400,400,-10,10,-10,10,3x+5) )}}}


y = <font color="magenta">0.5</font>x + 3 

That one has slope <font color="magenta">0.5</font>, which is also positive.  

Here is its graph:

{{{graph(400,400,-10,10,-10,10,.5x+3) }}}

Lines that go uphill to the right like this / have positive slopes.  
Lines that go downhill to the right like this \ have negative slopes.
