It depends on the systems of equations. I would stay away from elimination, go for substitution and graph only if asked.

The diagram shows two straight lines. Both lines intersect at point A. У y = 4x A х A y = -2 Identify the coordinates of point A
Semmy [17]

Answer:

Point A is at (-1/2,\, -2).

Step-by-step explanation:

The intersection (x,\, y) of two lines in a plane could be found by solving a linear system of two unknowns (x and y) and two equations (one for each line.)

In this question, the equation of the two lines are y = 4\, x and y = -2, respectively. The corresponding system of equations would be:

\left\lbrace \begin{aligned} & y = 4\, x \\ & y = -2\end{aligned} \right..

Solve this system for x and y:

  • y = (-2).
  • Substitute y = (-2) into the first equation and solve for x\!: x = (-1/2).

Therefore:

\left\lbrace \begin{aligned} & x = -\frac{1}{2} \\ & y = -2\end{aligned} \right..

Thus, the coordinates of this intersection (x,\, y) would be (-1/2,\, -2).
