Don't answer if you don't know a sports car is traveling on an express highway in germany at a speed of 90.00 km/h. the car moves into the fastest lane and increases its speed to 190.00 km/h in 12.00 s. what is the acceleration of the car for the 12.00 s? a. 7.50 km/h/s b. 8.33 km/h/s c. 15.80 km/h/s d. 100.00 km/h/s

The answer is b because 100 divided by 12 is 8.333333333333and so on.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
