**negative correlation**. Then i drew the

**line of best fit**. Then i used two points to find the

**slope**and my slope was -3.9/20. Then i used the

**point slope form**to write my equation y=-3.9/20x+-6.275. I used the graphing calculator to find the

**correlation coefficient**which was r=-.9921. I think the value of r tells the faster you drive the mileage will go down. The equation for best fit is y=-.204x+28.52. I predict that the mileage for a speed of 55 mph is 17 mpg. I also predict that the speed if the mileage is 28 mpg will be about 30mph.
