Exercises 86–88 will help you prepare for the material covered in the first section of the next chapter. a. Does (4, −1) satisfy x + 2y = 2? b. Does (4, -1) satisfy x- 2y= 6?

Guida verificata passo dopo passo

Identify the given point (4, -1) where x = 4 and y = -1.

For part (a), substitute x = 4 and y = -1 into the equation

x + 2 y = 2

. This means calculate

4 + 2 	imes (-1)

Simplify the left side of the equation after substitution to see if it equals 2.

For part (b), substitute x = 4 and y = -1 into the equation

x - 2 y = 6

. This means calculate

4 - 2 	imes (-1)

Simplify the left side of the equation after substitution to check if it equals 6.
