Question 1205149: Use the graph to solve the system of linear equations.
$-y=4
4x+y=1
Two lines are plotted on a coordinate plane. The first line passes through ordered pair 0 comma negative 4 and ordered pair 4 comma 0. The second line passes through ordered pair 0 comma 1 and ordered pair 1 comma negative 3. The lines cross through 1 comma negative 3.

Use the graph to solve the system of linear equations.
x-y=4......eq.1
4x%2By=1.....eq.2
start with graphing first line
x-y=4.......eq.1
given: The first line passes through ordered pair (0,-4) and ordered pair (4, 0)
both lines cross through (1,-3)
using this table
x|y
0|-4
4|0
1|-3

plot points and draw a line through


now, second line
4x%2By=1.....eq.2
The second line passes through ordered pair (0,+1) and ordered pair (1,-3).

x|y
0|1
1|-3
plot points and draw a line through
