Answer:
x=−2
Step-by-step explanation:
like so:
2x+4y=−4
...subract 2x from both sides:
4y=−2x−4
...divide both sides by 4:
y=(−x2)−1
Now, the y intercept is the value of y where x = 0 -
y=0−1=−1
For the x intercept, set y = 0 and solve for x:
0=(−x2)−1
x2=−1
x=−2
so now you have your x & y intercepts. On your graph, plot points (-2, 0) and (0,-1)
And draw your line extending through these points.
graph{y = (-x/2)-1 [-10, 10, -5, 5]}
