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!

1) Use the vertical line test. The vertical line used will intersect the line of the equation: at ONLY 1 point.
Thus, the equation: 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 ()
is > 0, or positive so the slope of the line of the equation: 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: .
