Question

what is the slope of

1.)13x-11y=-12

2.)9x-7y=-7

Answer 1

`Ax+By=C\\\\slope:m=-(A)/(B)\\\\\\1)\ 13x-11y=-12\\\\A=13;\ B=-11\\\\m=-(13)/(-11)=(13)/(11)\\\\\\2)\ 9x-7y=-7\\\\A=9;\ B=-7\\\\slope:m=-(9)/(-7)=(9)/(7)`

Answer 2

`the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\1)\\ \\ 13x-11y=-12 \ \ -13x\\ \\-11y=-13x -12 \ \ /:(-11)\\ \\y=(13)/(11)x+(12)/(11) \\ \\ m=(13)/(11)`



`2.)\\ \\9x-7y=-7 \ \ -9x \\ \\ -7y=-9x-7 \ \ /: (-7) \\ \\ y= (9)/(7) +1 \\ \\ m=(9)/(7)`
