Respuesta :
a.) (-10,-30) is a solution to the equation y = 3x
b.) (10,-86) is a solution to the equation y = -9x + 4
b.) (10,-86) is a solution to the equation y = -9x + 4
Answer:
For [tex]y=3x[/tex]
(-10,-30)
For [tex]y=-9x+4[/tex]
(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:
[tex]y(x)=3x[/tex]
For (-2,-9)
[tex]y(-2)=3(-2)=-6\neq -9[/tex]
This ordered pair doesn't satisfy the equation.
For (-8,-18)
[tex]y(-8)=3(-8)=-24\neq -18[/tex]
This ordered pair doesn't satisfy the equation.
For (-8,-3)
[tex]y(-8)=3(-8)=-24\neq -3[/tex]
This ordered pair doesn't satisfy the equation.
For (-10,-30)
[tex]y(-10)=3(-10)=-30[/tex]
This ordered pair satisfies the equation. Therefore is a solition of the equation [tex]y(x)=3x[/tex]
[tex]y(x)=-9x+4[/tex]
For (10,-86)
[tex]y(10)=-9(10)+4=-90+4=-86[/tex]
This ordered pair satisfies the equation. Therefore is a solition of the equation [tex]y(x)=-9x+4[/tex]
For (-4,-58)
[tex]y(-4)=-9(-4)+4=36+4=40 \neq -58[/tex]
This ordered pair doesn't satisfy the equation.
For (6,-41)
[tex]y(6)=-9(6)+4=-54+4=-50\neq -41[/tex]
This ordered pair doesn't satisfy the equation.
For (-6,57)
[tex]y(-6)=-9(-6)+4=54+4=58\neq 57[/tex]
This ordered pair doesn't satisfy the equation.
