Question

Can someone help me with this math equation? (Math 9, standard form of a line)

Answer 1

`\sf\\23.\ -8x+4y=5\\\textsf{Comparing with }Ax+By=C,\ A=-8,b=4\textsf{ and }C=5\\\textsf{Here, A is a negative number so the equation shown is not in the standard form.}`

`\sf\\\textsf{24. 19y + 4x = 22}\\\textsf{Comparing with Ax + By = C},\ A=4,\ B=19\textsf{ and }C=22\\\textsf{Here, A, B and C are all integers (not fractions or decimals) and A is a positive}\\\textsf{number. So the given equation is in the standard form.}`

`\sf\\\textsf{25. }19=23x-4y\\\textsf{or, }23x-4y=19\\\textsf{Comparing with }Ax+By=C,\ A=23,\ B=-4,\ C=19\\\textsf{Here, A is a positive number and A, B and C are all integers. So the given }\\\textsf{equation is in the standard form.}`

`\sf\\26.\ 3x-4y=(1)/(2)\\\textsf{Comparing with }Ax+By=C,\ A=3,\ B=-4\textsf{ and }C=(1)/(2)\\\textsf{Here, C is a fraction. Therefore, the given equation is not in the standard form.}`

`\sf\\27.\ x-y=22\\\textsf{Comparing with }Ax+By=C,\ A=1,\ B=-1\textsf{ and }C=22\\\textsf{Here, all A, B and C are all integers and A is a positive number. Hence the }\\\textsf{equation given is in the standard form.}`

`\sf\\28.\ 3x-(1)/(2)y=45\\\textsf{Comparing with }Ax+By=C,\ A=3,\ B=-(1)/(2)\textsf{ and }C=45\\\textsf{Here, B is a fractional number. So the given equation is not in the standard form.}`
