Question 687675
There are 2 usual forms you will find
a linear ( straight line ) equation in.
(1)
The standard form
{{{ ax + by = c }}}
(2)
The slope-intercept form
{{{ y = m*x + b }}}
---------------------
You need the slope-intercept form in
order to find the slope, which is {{{ m }}}.
---------------------
Suppose you are given:
{{{ 4x - 7y = 13 }}}
Subtract {{{ 4x }}} from both sides
{{{ -7y = -4x + 13 }}}
Divide both sides by {{{ -7 }}}
{{{ y = (4/7)*x - 13/7 }}}
----------------------
This is now in the slope-intercept form
and the slope is {{{ m = 4/7 }}}
----------------------
This is hard to see when the equation
is in the other form
Hope this helps
