What’s the slope of (-5,-18) & (15,3)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Solve for b. ab + c= d b= a + old ob=allc-ch b= (d-c/a
