Here are the fuel efficiencies (in mpg) of 10 new cars. 28, 24, 29, 18, 13, 43, 38, 14, 49, 32

What is the percentage of these cars with a fuel efficiency less than 28 mpg?

111

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
