Help me with these 2 problems Helen is it a bicycle race. She has already bike 10 miles and is now biking at a rate of 18 mph. Her distance as a function of time is shown in the graph.
1. Write an equation that represents the distance Helen has biker as a function of time.
2. Identify the slope and Y intercept and describe their meanings.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
