Step-by-step explanation:
A) For the city of Everettt, y-intercept represent the number of chrome books they started with.
y - intercept = 550
Everett started the 2016 year with 550 chrome books
B) y = 50x + 300
Explanation: They stared with 300 books at 2016. This will be the y-intercept
Rate of change = 50 books per year which will the slope
m = 50 and b = 300
y = mx + b
y = 50x + 300
Hint: y- intercept is where x-coordinate =0
<span>–10, –7.5, –5, –2.5, …
Is defined by the formula because the next term can be obtained by adding 2.5 to the current one.</span>
