Question 1010126


Find the {{{x-intercept}}} and {{{y-intercept}}}.

The general rules are:

    To find an {{{x-intercept}}}, let the value of {{{y}}} in the equation be equal to {{{zero}}}.
    Your {{{x-intercept}}} will be written as a point ({{{x}}},{{{0}}}) .
     
    To find a {{{y-intercept}}}, let the value of {{{x}}} in the equation be equal to zero.
    Your {{{y-intercept}}} will be written as a point ({{{0}}},{{{y}}}).
1. 
{{{y=x}}}
if {{{x=0}}}=>{{{y=0}}}->{{{y-intercept}}} is ({{{0}}},{{{0}}})
if {{{y=0}}}=>{{{x=0}}}->{{{x-intercept}}} is ({{{0}}},{{{0}}})

2. 
{{{y+x=4}}}
if {{{x=0}}}=>{{{y+0=4}}}=>{{{y=4}}}->{{{y-intercept}}} is ({{{0}}},{{{4}}})
if {{{y=0}}}=>{{{0+x=4}}}->{{{x-intercept}}} is ({{{0}}},{{{4}}})

3. 
{{{y=1}}}->{{{y-intercept}}} is {{{1}}}
->{{{x-intercept}}} does not exist
The horizontal line {{{y=1}}} will never cross the x-axis. A horizontal line (other than {{{y = 0}}}) will not have an x-intercept.
