The graph of the equation is

Step by step solution

Step 1. Given Information

Graph the equation by plotting points: $4 x + y = - 3$

Step 2. Find three points that are solutions to the equation.

First, solve the equation for y .

$4 x + y = - 3$

Subtract $4 x$ on both side

$4 x + y - 4 x = - 3 - 4 x y = - 3 - 4 x$

Step 3. Now the equation is y=−3-4xFinding the point by putting the values.

$x = 0 x = 1 x = 2 y = - 3 - 4 x y = - 3 - 4 x y = - 3 - 4 x y = - 3 - 4 \times 0 y = - 3 - 4 \times 1 y = - 3 - 4 \times 2 y = - 3 - 0 y = - 3 - 4 y = - 3 - 8 y = - 3 y = - 7 y = - 11$

Step 4. Plot all points in a rectangular coordinate system.Plot the points (0,-3), (1,-7), (2,-11)

Step 5. Draw the lines through the three points.
