X+Y=-11 solving linear equations by graphing
1 answer:
Answer:
the graph is attached
Step-by-step explanation:
This sort of equation makes it easy to find the x- and y-intercepts. Setting x to zero gives ...
y = -11 . . . . . the y-intercept
Setting y to zero gives ...
x = -11 . . . . . the x-intercept
You can plot these two points, then draw a line through them to complete the graph.
Every point on this line is a solution to the equation.
