Its an Identity, all real numbers are the answer.
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.
x = 9
Hope this helps you :)
Two equations for a horizontal line could be y = 1 & y = 5
Two equations for a vertical line could be x = 2 & x = 6
Horizontal lines are created when y is always equal to one number, while vertical lines are created when x is always equal to one number.
Hope this helps!
