Write the problem as a mathematical expression.
Subtract from both sides of the equation.
Use the quadratic formula to find the solutions.
Substitute the values, and into the quadratic formula and Simplify.
Simplify the numerator. Multiply by Simplify
Answer:
y = 25x - 85
Step-by-step explanation:
Every second (x) that passes by is 25 meters gained, and since she's 85 meters away from the safe distance still, the y intercept is -85.
Plot the points you found in part (b) on a suitable set of coordinates and draw a line through them. It might help your accuracy to use the y-intercept of 20 also.
The general form of the equation of the line shown would be x-y=0
