Question

Quiah saved $200 every month that she worked. Her savings is recorded in the data table below. What equation would best describe Quiah's savings?

Answer 1

y = 200x + 300

Explanation:

Plot the points on a graph and draw a line through the data points. Find the y-intercept and slope from the graph.

Answer 2

(1, 500) (2, 700)

(700-500)/(2-1)

200/1= 200

y - 500 = 200(x - 1)

y - 500 = 200x - 200

y = 200x + 300
