Question 235571
<font face="Garamond" size="+2">


In the first place, *[tex \LARGE \frac{3}{5}x\ +\ \frac{9}{2}] is not a line.  It is nothing but an expression involving the variable *[tex \Large x].


*[tex \LARGE y\ = \frac{3}{5}x\ +\ \frac{9}{2}] is an equation with a solution set consisting of ordered pairs that, when graphed in *[tex \Large R^2], form a straight line.


The slope of the line is the coefficient on *[tex \Large x].  The *[tex \Large y]-intercept is the ordered pair *[tex \Large \left(0,\,b\right)], where *[tex \Large b] is the constant term in the equation.
