Table of Values
Values of Function
X = 0, 1, 2
Ya = 3, 6, 9
Yb = 18, 13.5, 9
Which of the following systems of linear equations does the table of values represent?
(1 point)
У = 3x + 3
3 =-4.5x +18

y = 3х + 3
y = 4.5x - 18

y =-3x +3
Y = 4½x + 18

y = 3х +3
y= 4.5x + 18

Answer 1

Ya: slope = 6−3 = 3, y-intercept = 3 → y = 3x + 3.
Yb: slope = 13.5−18 = −4.5, y-intercept = 18 → y = −4.5x + 18.

So the system is y = 3x + 3 and y = −4.5x + 18 (choice 1, interpreting the second line as y = −4.5x + 18).
