Estimate the solution to the system of these linear equations based on the graph. Y=-5x+7

Y=-2x+10

1 answer

To estimate the solution to the system of equations based on the given equations \( y = -5x + 7 \) and \( y = -2x + 10 \), we need to find the point where the two lines intersect.

Step 1: Finding the Intersection

The intersection point can be found by setting the two equations equal to each other:

\[ -5x + 7 = -2x + 10 \]

Step 2: Solve for \( x \)

Rearranging the equation:

\[ -5x + 2x = 10 - 7 \] \[ -3x = 3 \] \[ x = -1 \]

Step 3: Solve for \( y \)

Now we'll substitute \( x = -1 \) back into either of the original equations to find \( y \). We'll use the second equation:

\[ y = -2(-1) + 10 \] \[ y = 2 + 10 \] \[ y = 12 \]

Step 4: Write the Solution

The solution to the system of equations, which is the point of intersection, is:

\[ (x, y) = (-1, 12) \]

Summary

The estimated solution based on the system of equations is \( (-1, 12) \).
