Question 1007939: The following question I had is
Is it a function? How would I know?
What type of slope would it be? How would I know?
What is the y-intercept how could I find it using this type of question?
F(x) = 3/7x - 320
This is all for one math problem thank you so much for taking the time to help me
I have a test on this soon so please please help!

The spacings use make the equation look like F%28x%29=%283%2F7%29x-320. Can you imagine or visualize the graph? Try the Vertical Line test. More than one intersection or not?

Yes, a function.
Slope-Intercept form, so you should recognize y-intercept is -320.

f%28x%29+=+%283%2F7%29x+-+320____y+=+%283%2F7%29x+-+320

1) Use the vertical line test. The vertical line used will intersect the line of the equation: f%28x%29+=+%283%2F7%29x+-+320 at ONLY 1 point. 

   Thus, the  equation: f%28x%29+=+%283%2F7%29x+-+320 represents a FUNCTION.

2) A linear equation with an x-coefficient that's < 0 (negative) will have a negative slope (sloping downwards), while a linear equation

   with an x-coefficient that's > 0 ((positive) will have a positive slope or one that slopes upward. In this case, the coefficient of x (3%2F7)

   is > 0, or positive so the slope of the line of the equation: f%28x%29+=+%283%2F7%29x+-+320 slopes upward.

c) The y-intercept is at the point on the y-axis where the graph of the line intersects the y-axis. To get this, substitute 0 for x and solve for y. 

   If the equation is in "y = mx + b" form, as this one is, then the y-intercept is simply "b." Looking at this equation, the y-intercept is: highlight_green%28-+320%29.
