Question 41928
<pre><font size = 4><b>what does the equation y = mx + c mean?

It means a straight line with slope 3 and y-intercept (0,c)

For instance y = 2x - 3 is a straight line with slope 2 and
y-intercept (0,-3), and has this graph:

{{{ graph( 300, 300, -4, 4, -4, 4, 2x-3) }}}

For instance y = -4x + 1 is a straight line with slope -4 and
y-intercept (0,1), and has this graph:

{{{ graph( 300, 300, -4, 4, -4, 4, -4x+1) }}}
