what is the equation for coordinates (-4,4) and (4, -3)

Question

i need to know how how to get the equation for these 2 coordinates on the coordinate plane... help ASAP.

 

Answer 1

Cross multiplication.

8y-32 = -7x-28

Add 32 to each side.

8y = -7x+4

Divide to each side by 8.

y = (-7/8)x+1/2.

Equation for given coordinates is y = (-7/8)x+1/2.
