Question

The line passes through the points (0, 50) (0, 50) and (5, 100) (5, 100) . What situation could match the graph? Angel has $100 and she saves $10 a week. Angel has $50 and she saves $15 a week. Angel doesn't have any money saved, but she saves $10 a week. Angel has $50 and she saves $10 a week. 1 2 3 4 5

Answer 1

(0,50)(5,100)
slope = (100 - 50) / 5 - 0) = 50/5 = 10

y = mx + b
slope(m) = 10
(0,50)...x = 0 and y = 50
now we sub and find b, the y int
50 = 10(0) + b
50 = b

equation is : y = 10x + 50

Angel has 50 and she saves 10 a week <===

Answer 2

The slope:
(100-50)/(5-0)
50/5
10

y intercept is 50 because one of the coordinates is (0, 50)

The equation is: y=10x+50

This means that they have to start at 50 and increase by 10 each week, The only one that does that is Angel.

Hope this helps :)
