Question

Identify the correct x intercept and y intercept of the equation x + 7y = -21.

x intercept = (3, 0); y intercept = (0, 21)

x intercept = (-3, 0); y intercept = (0, -21)

x intercept = (21, 0); y intercept = (0, 3)

x intercept = (-21, 0); y intercept = (0, -3)

Answer 1

x intercept = (-21, 0); y intercept = (0, -3)

Answer 2

To get the x intercept, solve for when y = 0.
To get the y intercept, solve for when x = 0.

@goformit100 Please don't give out the answer like that, especially without showing any work. It doesn't help anyone learn.

Answer 3

sorry @Wired

Answer 4

x intercept = (-3, 0); y intercept = (0, -21)

Answer 5

@Muskan You have it reversed:
http://en.wikipedia.org/wiki/Y-intercept
a y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system.[1] As such, these points satisfy x=0.
