Question 170589
{{{y=(-1/2)x+(5/2)}}} ---------> this follows Slope-Intercept form, {{{y=mx+b}}}
{{{Slope=m=(-1/2)}}} & {{{Yintercept=(5/2)}}}
{{{f(y)=0}}}
{{{(1/2)x=5/2}}} --->{{{cross(1/2)x/cross(1/2)=(5/2)/(1/2)}}}
{{{x=(5/cross(2))(cross(2)/1)=5}}}, x-intercept
See graph:
{{{drawing(300,300,-7,7,-7,7,grid(1),graph(300,300,-7,7,-7,7,(-1/2)x+(5/2)),blue(circle(5,0,.15)),blue(circle(0,5/2,.15)))}}}
.
Thank you,
