A line has a slope of -3/7 and its y-intercept is (0,13). What is its x-intercept?

We have  the  equation

 

y = (-3/7)x  +  13                     

 

To  find  the x intercept , set  y  =  0   and  solve  for x

 

0   =   (-3/7)x  + 13

 

-13  = (-3/7) x

 

(-13)  /( -3/7)  = x   

 

13  *  7  / 3    =  x

 

91/3   =   x intercept
