Misty correctly determined the equation of the linear function represented by the table of values below to be y=-2x+9 in slope-intercept form by using the ordered pairs (1, 7) and (2, 5).

Misty correctly determined the equation of the linear function.

Step-by-step explanation:

It is given that the equation of linear function determined  by Misty is

We have check that either she is correct or not.

It is given that the linear function passing through the points (1, 7) and (2, 5).

If a linear function passing through two points, then the equation of linear function is

The equation of line is

Since the calculated equation is same as the given equation, therefore we can say that Misty correctly determined the equation of the linear function.

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
