Given the equation:
8x + 7y = -50
We will check the options to find which order pair is the solution of the equation
Point (-6 , -1)
8 * -6 + 7 * -1 = -48 - 7 = -55 ≠ -50
Point ( 0 , -6)
8 * 0 + 7 * - 6 = -42 ≠ -50
Point (-6, 0 )
8 * - 6 + 7 * 0 = -48 ≠ -50
Point (-1 , -6)
8 * -1 + 7 * -6 = -8 - 42 = -50
so, the order pair which is a solution for the equation is (-1 , -6 )
