Answer:
f^-1(x) = 1/5x + 1/5
Step-by-step explanation:
Switch the x and y values:
y = 5x - 1
x = 5y - 1
Put the equation back into y = form:
x = 5y - 1
x + 1 = 5y
1/5x + 1/5 = y
y = 1/5x + 1/5
f^-1(x) = 1/5x + 1/5
To plot a point on a graph, you need the x and y coordinates.
In this case, the x-coordinate is 2 and the y-coordinate is 2 thus you can plot
(2,2) on a graph.
To get the equation of a line, you need the slope m of the line, a point and another imaginary point (x,y). So in this question you still need the slope to find the equation.
The equation is : No
Answer
1. The point can be plotted on a graph
2. No, the equation can not be determined because the gradient is not known.
Answer:
250 miles apart. we know this because they were traveling 125 miles an hour.
