Mr. Goldstein is driving to Houston. The equation y = -45x + 270 represents the numbers of miles that he still has to travel after driving for x hours. What is the slope of the line and what does it represent in this situation? 0 270 and it represents the driving miles per hour O 270 and it represents how many miles he had to drive 0 -45 and it represents the number of driving miles per hour 0-45 and it represents the number of miles he had to drive

Respuesta :

Given the equation:

y = -45x + 270

To find th slope, use the slope intercept form:

y = mx + b

Where m is the slope.

Now, compare both equations:

y = mx + b

y = -45x + 270

The slope is of the line:

m = -45

The slope represents the number of driving miles per hour.

Therefore, the slope is -45 and it represents the number of drumber of dr
