The answer to this problem
stepan [7]
Let's assume that you are to graph the inequality. 
1.  Graph -3x + 4y = 12.  Note that the x-intercept is (-4,0) and the y-intercept is (0,3).  Use a dashed line, not a solid line, due to the ">" sign.
2.  Choose a test point (e. g., (0,1) ) and subst. these coordinates into -3x + 4y = 12.  Is the equation then true or false?  If true, shade the area (on one side of -3x + 4y = 12 or the other) in which the test point (0,1) lies.  If false, shade the other side of -3x + 4y = 12.

Write the equation in slope-intercept form and find the equation of a line through the given point (a) parallel and (b) perpendi
skelet666 [1.2K]

keeping in mind that parallel lines have the same exact slope, hmmm what's the slope of 4x - 2y = 3 anyway?  well, let's put it in slope-intercept form firstly.


\bf 4x-2y=3\implies 4x-3=2y\implies \cfrac{4x-3}{2}=y&#10;\\\\\\&#10;\cfrac{4x}{2}-\cfrac{3}{2}=y\implies \stackrel{slope}{2}x-\cfrac{3}{2}=y


a)


so we're looking for a line whose slope is 2 and passes through 2,1.


\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{1})~\hspace{10em}&#10;slope = m\implies 2&#10;\\\\\\&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-1=2(x-2)&#10;\\\\\\&#10;y-1=2x-4\implies \blacktriangleright y=2x-3 \blacktriangleleft


b)


\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}}&#10;{\stackrel{slope}{2\implies \cfrac{2}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{1}{2}}\qquad \stackrel{negative~reciprocal}{-\cfrac{1}{2}}}&#10;\\\\[-0.35em]&#10;\rule{34em}{0.25pt}


\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{1})~\hspace{10em}&#10;slope = m\implies -\cfrac{1}{2}&#10;\\\\\\&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-1=-\cfrac{1}{2}(x-2)&#10;\\\\\\&#10;y-1=-\cfrac{1}{2}x+1\implies \blacktriangleright y=-\cfrac{1}{2}x+2 \blacktriangleleft
