What would x+y=9 and x+3=y be in slope intercept form?

x + y = 9

y = -x + 9

x + 3 = y

y = x + 3

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
