What is the rate of change of a linear function that includes the points (5, 2) and (9, 4)?

The rate of change for this function is 1/2.

In order to find the rate of change, you use the slope equation.

m (slope) = (y2 - y1)/(x2 - x1)

m = (4 - 2)/(9 - 5)

m = 2/4

m = 1/2

answer: -2+√x,-2-√x

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
