Question 198499

The x - intercept of the equation y = 6x + 4 is -2/3.


That is right. But what is the question?
Maybe you want to graph it?



Let Fy=0
{{{0=6x+4}}} ----> {{{6x=-4}}} ---> {{{cross(6)x/cross(6)=-4/6}}}
{{{red(x=-2/3)}}}


Let Fx=0
{{{y=6(0)+4=0}}}
{{{red(y=4)}}}


Then we plot the points, (-2/3,0) & (0,4)
{{{drawing(300,300,-5,5,-5,8,grid(1),graph(300,300,-5,5,-5,8),blue(circle(-2/3,0,.12)),blue(circle(0,4,.12)))}}}--->{{{drawing(300,300,-5,5,-5,8,graph(300,300,-5,5,-5,8,6x+4),blue(circle(-2/3,0,.12)),blue(circle(0,4,.12)))}}}
