Which statement could be used to explain why f(x) = 2x – 3 has an inverse relation that is a function? O The graph of f(x) passes the vertical line test.
O f(x) is a one-to-one function.
The graph of the inverse of f(x) passes the horizontal line test.
O f(x) is not a function.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
