Question

The instructor had saved $3,500 and rents an apartment for $275 monthly. He believes the point (6, 1850) would be on the equation of the line.

Answer 1

Sample Answer: Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.

Explanation:

Answer 2

y = 275x + 3500
1850 = 275(6) + 3500
1850 = 1650 + 3500
1850 = 5150...(incorrect)

(6,1850) is not a point in this line
