Answer:
Equation for these two coordinates: y=-4x-15
Explanation:
If you can, try using desmos and use the 'y='.
I got y=-4x by observing if the line is symmetrical to the dots.
The line was above, so I subtracted a number like 12, 13, 14, and 15.
This is how I got y=-4x-15.
If the dots are positive to each other climbing up like this /, use a positive number. If it is the opposite, use a negative number.
(I hope this helps.)
