Question

The equation of the graphed line is 2x – y = –6. What is the x-intercept of the graph?

Answer 1

U can either look at ur graph...and where the line crosses the x axis is ur x intercept...which is (-3,0)

OR

take ur equation and sub in 0 for y, and solve for x, ur x intercept.
2x - y = -6
2x - 0 = -6
2x = -6
x = -6/2
x = -3.....so ur x intercept is (-3,0)

Answer 2

The x-intercept is: -3
2x - y = -6 
2x = -6 (cover the -y with hand: mitten rule)
x = -3
