QUESTION:

1. Anna plotted points S (3, 3); T (7,3); A (7,-1). What should be the coordinates of R so that STAR is a square?

2.What is the value of y in the equation -3x + y = 4, when x = -2?

ANSWER:

1. The coordinates of R should be (3, - 1)

from point S we go 4 spaces down to form a square of side 4.

2. When X= -2

-3x + y= 4

-3 (-2) + y= 4

6+y = 4

y+4= -6

y= -2

ANSWER: When x= -2, y= -2

2. What is the value of y in the equation -3x + y = 4, when x = -2?

ANSWER:

-3x + y = 4, when x = -2

Substitute x = -2

-3 x (-2) + y= 4

y= 4 - 6

y= - 2

ANSWER: - 2
