I have this equation y+x=-7 I have to graph my answers to find out what my y is. I have tried everything, and I cannot get my points to cross. Any help would be great.
y+x=-7
will give you a straight line. Do you have another line or set of points it needs to cross?
y=-x-7
what do you mean the points cross. This is a line, it never crosses itself.
To graph the equation y + x = -7, you can use a coordinate plane. Here are the steps to graph the equation and find the points where y is:
1. Convert the equation to slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. In this case, the equation already looks like y + x = -7.
2. Subtract x from both sides to isolate y: y = -x - 7.
3. Now you have the equation in the form y = mx + b, where m (the slope) is -1 and b (the y-intercept) is -7.
4. To graph the equation, start by finding the y-intercept. Plot the point (0, -7), which is where the line crosses the y-axis.
5. Next, use the slope to find additional points. The slope of -1 means that for every one unit you move to the right, you move one unit down. So, starting from the y-intercept (0, -7), move one unit to the right and one unit down, which gives you the point (1, -8).
6. Repeat the process to find more points. For example, move one unit to the left and one unit up from the y-intercept to get (-1, -6).
7. Plot all the points you've found on the coordinate plane.
8. Finally, draw a straight line through the plotted points. This line represents all the values of x and y that satisfy the given equation.
By following these steps, you should be able to graph the equation y + x = -7 and find the points where y is located. If you are still having trouble, please let me know and I can assist you further.
