Find a slope if it exists, please.
9x-y=9
y=9x-9
That's called the slope-intercept form, so read off the slope.
To find the slope of the equation 9x - y = 9, we need to rearrange the equation into slope-intercept form, which is in the form y = mx + b. In this form, m represents the slope.
Let's transform the given equation to slope-intercept form:
9x - y = 9
First, let's isolate the y term by subtracting 9x from both sides:
-y = -9x + 9
Next, multiply every term by -1 to make the y term positive:
y = 9x - 9
Now we can see that the equation is in slope-intercept form, where the coefficient of x (9) is the slope of the line. Therefore, the slope of the line represented by the equation 9x - y = 9 is 9.
