What is the equation of the line from the table of values?
A. y = x + 2
B. x= −y − 2
C. y= x − 2
D. x = y + 2

Answer 3

1Because we have coordinates of a point on the line and slope, let's use Point-Slope Form of linear equation

y - y1 = m(x -x1)

y - (- 4) = (1/2)(x - 6)

y + 4 = (1/2)x - 3

y - (1/2)x = - 3 - 4

Let's multiply both sides of equation by (- 2)

x - 2y = 14

~~~~~~~~~
6 - 2*(- 4) = 14
6 + 8 = 14
14 = 14
