1. Problem Description

The problem asks to find the x and y intercepts of the equation 2x+y+4=02x + y + 4 = 0 and then sketch the graph of the equation.

2. Solution Steps

First, we need to find the x-intercept. The x-intercept is the point where the graph crosses the x-axis, meaning y=0y = 0.
Substitute y=0y = 0 into the equation 2x+y+4=02x + y + 4 = 0:
2x+0+4=02x + 0 + 4 = 0
2x=42x = -4
x=2x = -2
So, the x-intercept is (2,0)(-2, 0).
Next, we need to find the y-intercept. The y-intercept is the point where the graph crosses the y-axis, meaning x=0x = 0.
Substitute x=0x = 0 into the equation 2x+y+4=02x + y + 4 = 0:
2(0)+y+4=02(0) + y + 4 = 0
0+y+4=00 + y + 4 = 0
y=4y = -4
So, the y-intercept is (0,4)(0, -4).
Now that we have the x and y intercepts, we can sketch the graph. We have two points: (2,0)(-2, 0) and (0,4)(0, -4). We can plot these points on the coordinate plane and draw a straight line that passes through both points.

3. Final Answer

x-intercept: (2,0)(-2, 0)
y-intercept: (0,4)(0, -4)
The equation of the line is 2x+y+4=02x+y+4=0. The graph is a straight line passing through (2,0)(-2,0) and (0,4)(0,-4).
