Find the slope and y-intercept.x = –8
The reason I am asking so many questions is all I have is a textbook and not an instructor, is online course. The textbook is like reading greek to me and I just do not understand algebra, or math either. So I thank you for helping and understanding my dilemna. And I am smart in other areas, just not math.

x = - 8
yes, but no one will communicate, the instructor only shows up once a week and does not help. has been hard for me.

sorry I can't help with your question, but doesn't the course have any resources? Ways to communicate with other students or the instructor?

The equation x = -8 has no slope and no y-intercept.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To help a little with slope and y-intercept, the slope-intercept form of a linear equation is y = mx + b where m is the slope and b is the y-intercept.
If you can solve an equation for y, you can quickly know the slope and the y-intercept.
The slope is the steepness of a line and the y-intercept is the point at which the line crosses the x-axis (which is where the x value is equal to zero).
In your equation did not have a y, it has NO slope. and since x can not equal zero in this equation, you have NO y-intercept.

For increasing cubic binomials the final formulation is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

The equation
x = -8
is a vertical line that passes through the coordinate (-8,0).
A vertical line has no defined slope, and this line does not have a y-intercept.

To determine the y-intercept you need a point and slope.
i.e. (-8, ?). Once you draw your slope using those two bits of information, you can determine the y-intercept.

This is a straight line up at x= -8. It does not cut the y-axis thus there is no y-intercept. The gradient is undefined.
