Part 1
a. Assume that the relationship between​ time, x, and number of​ electric-powered vehicles,​ y, is linear. Write an equation in​ slope-intercept form describing this relationship. Use ordered pairs of the form​ (years past 2012, number of​ vehicles).
The equation is enter your response here.

Answer 1

Answer: Using the two given points (0, 97507) and (5, 225317), we can find the slope:

slope = (225317 - 97507) / (5 - 0) = 25662

Then using the point-slope form of a line with the point (0, 97507):

y - 97507 = 25662x

Simplifying and putting in slope-intercept form:

y = 25662x + 97507

Therefore, the equation in slope-intercept form is y = 25662x + 97507.
