The line drawn for a scatter plot may not always be the line of best fit. But you can change it to a line of best fit by adjusting its y-intercept and slope. In this activity, you will change lines to better fit the data.
Part A
How could you change the slope and the y-intercept of the line in this graph to better fit the data? (Hint: Visualize what the best fit line would look
like, and then describe how to transform the existing line to that one.)

try and move the line to touch more dots.

Step-by-step explanation:

then salve for y intersept

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
