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. Is he correct? Explain how to check if a point is on a line

Respuesta :

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.



Yes the instructor is correct given the calculation that has been done below.

How to solve to know the instructor is correct

We have Amount saved = $3500

The amount that is rented = $275

The point on the line is given as 6 and 1850

We have to person the following operation

3500 - 275*6

= 3500 - 1650

= 1850

The solution is 1850 while the multiplication factor is 6. Hence the instructor is right.
