Answer:

x=3,0

Step-by-step explanation:

10x+y=30

The x-intercept is when y=0, so substitute 0 in and solve for x.

10x+0=30

10x=30

x=3

Coordinates: (3,0)

The y-intercept is when x=0, so substitute 0 in and solve for y.

10(0)+y=30

0+y=30

y=30

Coordinates: (0,30)

Or, if you prefer, seperate the y.

10x+y=30

Subtract 10x from each side

y=-10x+30

And substitute the 0 in, the answer will be the same.
