Question

Solve the equation, using the domain of x = {-1, 0, 2}.  Write your solutions as a set of ordered pairs. Do not type any spaces.  Where needed, round to two decimal places.

2x + 3y = 7

campbell_st · Answer

substitute the domain values 

but 1st rewrite the equation

$$y = \frac{1}{3}(7 - 2x)$$

x = -1 y = 3     x = 0 y = 7/3     x = 2 y = 1

ordered pairs

(-1,3) (0, 7/3), (2, 1)
