Calculate the slope of the equation passing through the points (-1, -9) and (1, 11).

10

Step-by-step explanation:

The formula to find slope with two ordered pairs is: . So inserting your numbers, you would do 11- (-9) or 11+9. Your answer for the numerator is 20. Next you do 1- (-1) or 1+1. Your denominator is 2. So your slope is 20/2 or simplified 10.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
