Answer:
For \(y=3x\)
(-10,-30)
For \(y=-9x+4\)
(10,-86)
Explanation:
If a pair of points satisfies a given equation, then it can be concluded that the pair of points is a solution of the equation. So in order to determine which ordered pair is a solution of the equation provided, we need to evaluate every one them into the equation:
\(y(x)=3x\)
For (-2,-9)
\(y(-2)=3(-2)=-6
eq -9\)
This ordered pair doesn't satisfy the equation.
For (-8,-18)
\(y(-8)=3(-8)=-24
eq -18\)
This ordered pair doesn't satisfy the equation.
For (-8,-3)
\(y(-8)=3(-8)=-24
eq -3\)
This ordered pair doesn't satisfy the equation.
For (-10,-30)
\(y(-10)=3(-10)=-30\)
This ordered pair satisfies the equation. Therefore is a solition of the equation \(y(x)=3x\)
\(y(x)=-9x+4\)
For (10,-86)
\(y(10)=-9(10)+4=-90+4=-86\)
This ordered pair satisfies the equation. Therefore is a solition of the equation \(y(x)=-9x+4\)
For (-4,-58)
\(y(-4)=-9(-4)+4=36+4=40
eq -58\)
This ordered pair doesn't satisfy the equation.
For (6,-41)
\(y(6)=-9(6)+4=-54+4=-50
eq -41\)
This ordered pair doesn't satisfy the equation.
For (-6,57)
\(y(-6)=-9(-6)+4=54+4=58
eq 57\)
This ordered pair doesn't satisfy the equation.
