type the correct answer in each blank. the line of best fit represents the number of miles jean covered at different speeds during a trip. if the speed is represented by x and the distance covered is represented by y, the equation of the best line of fit is y =(blank) . she covered about (blank) miles at the speed of 50 miles per hour.

The equation of the best line of fit is y = 2x

Step-by-step explanation:

The relationship between y and x is

y = mx + c

Where m = slope of the line

And c = intercept

At 50 miles per hour she has already covered a distance of 100 miles from the graph

We can use this to calculate the slope of the line using the coordinates (0,0) (50,100)

Slope m is calculated as;

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

Where y2 = 100, x2 = 50

y1 = x1 = 0

Substitute these values

So m = (100 - 0)/(50 - 0)

m = 100/50

m = 2

Since there's no intercept, c = 0

The equation y = mx + c becomes

y = 2x + 0

y = 2x

b.an increase in a causes b to decrease
