The equation of a line is  −6x−2y= −18.

What is the  x-intercept of the line?

-6x - 2y  =  -18

 

The x-intercept is the  x  value when  y = 0 ........so plug in  0  for  y  and solve for  x  .

 

-6x - 2(0)  =  - 18

 

-6x  =  -18

 

x  =  3            The x-intercept is  3 .  Here's a graph that shows this.

 

----------

 

x + 4y  =  15

 

The y-intercept is the  y  value when  x = 0 ........so plug in  0  for  x  and solve for  y  .

 

0 + 4y  =  15

 

4y  =  15

 

y  =  15/4  =  3.75         The y-intercept is  3.75 .  Here's a graph that shows this.
