Hello, Dragon!

Did you make a sketch?

Code:

* (-3,8) |

**Game plan**

The line contains the points (-3,8) and (6,-4).

. . We want the equation of that line.

Then we want its x-intercept and y-intercept .

. . Then we want the distance .

The slope of line is: .

The equation of the line through (6,-4) with slope is:

. .

For the -intercept, let and solve for

. . . . . -intercept:

For the -intercept, let and solve for

. . . . . -intercept:

The distance from to is:

. .
