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
