Question

При каких значениях а точка М(а; -2а) принадлежит графику функции у = -4х - 1

Answer 1

-2а=-4а-1
-2а+4а=-1
2а=-1
а=-0.5

Answer 2

Finding the Point of Intersection

To find the values of a for which the point M(a, -2a) belongs to the graph of the function y = -4x - 1, we can substitute the coordinates of the point M into the equation and solve for a.

Substituting the coordinates of M(a, -2a) into the equation y = -4x - 1 gives us: -2a = -4a - 1

Solving for a: -2a = -4a - 1 2a = -4a - 1 2a + 4a = -1 6a = -1 a = -1/6

Therefore, the point M(-1/6, 1/3) belongs to the graph of the function y = -4x - 1.
