In order to answer, I would first need to know Jana's speed, not that she biked at a constant rate.
Equation would be b = 14m
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
I’d help but the image isn’t working its all blurry on my end fam sorry
10-11= -1 You could also input this number on a calculator
