Math Problem Statement

Find the intersection point of the two lines: g: y = -5x - 1 and h: y = -7x - 3.

Solution

The image shows two linear equations labeled gg and hh:

  • g:y=5x1g: y = -5x - 1
  • h:y=7x3h: y = -7x - 3

To find the intersection point of these two lines, we solve the system of equations by setting g=hg = h:

5x1=7x3-5x - 1 = -7x - 3

Step-by-Step Solution:

  1. Simplify the equation: 5x+7x=3+1-5x + 7x = -3 + 1 2x=22x = -2

  2. Solve for xx: x=1x = -1

  3. Substitute x=1x = -1 into either equation to find yy. Using g:y=5x1g: y = -5x - 1: y=5(1)1y = -5(-1) - 1 y=51=4y = 5 - 1 = 4

Intersection Point:

The intersection point is: (x,y)=(1,4)(x, y) = (-1, 4)
