Question 1003904
{{{ y + 3 = 2*( x-2 ) }}}
Whatever you do to one side of
the equation, you have to do to the
other side also
------------------
The goal is to get the {{{ y }}} on
the left side alone
------------------
Subtract {{{ 3 }}} from both sides
{{{ y = 2*( x-2 ) - 3 }}}
-------------------
Now simplify the right side
{{{ y = 2x - 4 - 3 }}}
{{{ y = 2x - 7 }}}
This is now in the form called
" slope-intercept form " which
makes it easier to plot
------------------------
The slope is {{{ 2 }}} and the y-intercept is {{{ -7 }}}
Here's the plot:
{{{ graph( 400, 400, -10, 10, -10, 10, 2x - 7 ) }}}
The slope is how steep the line is and the
y-intercept is where it crosses the y-axis
-----------
Hope this helps
