Math Problem Statement

Solution

The image you've uploaded contains a system of linear equations that need to be solved by graphing. Here are the equations provided:

  1. y=12x+4y = -\frac{1}{2}x + 4
  2. y=34x1y = \frac{3}{4}x - 1

You have already plotted the two lines on the graph. The solution to the system is the point where these two lines intersect.

Analyzing the Graph:

  • The two lines intersect at the point (4,2)(4, 2), as you've noted on the graph.
  • This point (4,2)(4, 2) is the solution to the system of equations because it satisfies both equations.

Verification:

Let's verify by substituting x=4x = 4 and y=2y = 2 into both equations to ensure it satisfies them.

  1. First equation: y=12x+4y = -\frac{1}{2}x + 4 2=12(4)+4=2+4=22 = -\frac{1}{2}(4) + 4 = -2 + 4 = 2 This is true.

  2. Second equation: y=34x1y = \frac{3}{4}x - 1 2=34(4)1=31=22 = \frac{3}{4}(4) - 1 = 3 - 1 = 2 This is also true.

Since the point (4,2)(4, 2) satisfies both equations, it is indeed the correct solution.
