Question

Write a linear equation in standard form for the line that goes through (4,3)

and (8,2).
A. X + 4y = 16
O B. y-3 -- 4(x-4)
O C. X+ 4y = 8
O D. -x + 4y = 16

Answer:

A. x + 4y = 16

Explanation:

Equation B is in point-slope form, not standard form. Equation D has a negative leading coefficient, so is not in standard form, either.

You only need to try the values for the first point to see whether equation A or equation C is the one you want.

x + 4y = 4 +4·3 = 4 +12 = 16 . . . . . matches equation A
