Every ordered pair can be read as (x,y). The equation for choice a would be 5*3-(-4)=19 which can be simplified to 15+4=19, which is true. B is incorrect because 5*-4 is negative, and to subtract four from that does not equal a positive number. C is also incorrect, because 5*4-(-4) is bigger than 19, and D ends up being negative by multiplying 5 and -4. Adding three does not make -20 positive.

Each ordered pair can be substituted into the equation as (x,y). For example, the option c, (4,-4), can be substituted as 4 for x and -4 for y into the equation 5x - y = 19, which yields 5 * 4 - ( - 4 ) = 19 and reduces to 24 = 19. Since this equation is not true, option c is not a solution.

in simple terms attempt all of them: A: -86 = -9(10) + 4 -86 = -ninety + 4 -86 = -86 --> definite, that's genuine. So A is your answer. yet in simple terms to envision... B: -fifty 8 = -9(-4) + 4 -fifty 8 = -36 + 4 -fifty 8 = -32 --> No. C: -40-one = -9(6) + 4 -40-one = -fifty 4 + 4 -40-one = -50 --> No. D: fifty seven = -9(-6) + 4 fifty seven = fifty 4 + 4 fifty seven = fifty 8 --> No.
