Question 168423
{{{x-y+4=0}}} --------------> A Line Equation
We follow Slope-Intercept form as we find the x & y intercepts: {{{y=mx+b}}}
It follows,
{{{y=x+4}}} ----> {{{Slope=m=1}}}; {{{Yintercept=b=4}}}
f(y)=0:
{{{x=-4}}}, x- intercept
.
As we see below,
{{{drawing(300,300,-5,5,-5,6,grid(1),graph(300,300,-5,5,-5,6,x+4),circle(-4,0,.15),circle(0,4,.15),red(circle(-3,1,.09)),red(circle(-2,2,.09)),red(circle(-1,3,.09)),red(circle(1,5,.09)))}}}----> See x & y intercepts (-4,4). Also marked in "red" dots the slope ---> distance between points=1
.
Thank you,
