graph y=-7x -1 ????im super confused
it is the equation of a straight line, right?
so, plot two points.
when x=0, y = -7*0 - 1 = -1
when x=1, y = -7*1 - 1 = -8
so, plot the points (0,-1) and (1,-8) on some graph paper.
Then draw the line that goes through those two points.
If you cannot plot points, you have some catching up to do.
how did you do this tho i can not figure it out
To graph the equation y = -7x - 1, we can start by plotting a few points and then connecting them to form a line.
To find the points, we can choose different x-values and substitute them into the equation to get the corresponding y-values. Let's choose three x-values and find their respective y-values:
When x = 0:
y = -7(0) - 1
y = 0 - 1
y = -1
So, we have the point (0, -1).
When x = 1:
y = -7(1) - 1
y = -7 - 1
y = -8
So, we have the point (1, -8).
When x = -1:
y = -7(-1) - 1
y = 7 - 1
y = 6
So, we have the point (-1, 6).
Now we can plot these points on a graph. The x-coordinate represents the horizontal axis, and the y-coordinate represents the vertical axis.
After plotting the points (0, -1), (1, -8), and (-1, 6), you can draw a straight line passing through them. This line represents the graph of the equation y = -7x - 1.
Here is the graph for your equation:

I hope this helps! Let me know if you have any further questions.
To understand the equation y = -7x - 1, we need to interpret it as a linear equation in slope-intercept form, which is y = mx + b. In this form, "m" represents the slope of the line and "b" represents the y-intercept.
In your equation, the coefficient of "x" is -7, which gives us the slope of the line. Since the coefficient is negative, it means that the line is decreasing as x increases. The y-intercept is -1, which is the point where the line intersects the y-axis (when x = 0).
To graph this equation, we can start by plotting the y-intercept, which is the point (0, -1). From there, we can use the slope to find additional points. The slope of -7 means that for every increase of 1 in x, y will decrease by 7. So, starting from (0, -1), we can move 1 unit to the right and 7 units downward to find the next point, which would be (1, -8).
By continuing this process, we can find more points, such as (2, -15), (3, -22), and so on. Once we have multiple points plotted, we can draw a straight line that passes through all of them to represent the graph of the equation y = -7x - 1.
Alternatively, you can use a graphing calculator or software to plot the equation for you. Simply enter the equation y = -7x - 1 into the calculator or software, and it will generate the graph for you.
