What is the slope of the line given by 4x = 0 by 5y = 0?
How do I solve this?
1. 4X = 0.
Divide both stdes by 0:
X = 0 = A constant,
Since X is constant, Y is changing.
Therefore, we have a vertical line.
Since X = 0 for all values of Y,the
line lies on the Y-axis and the slope
is undefined:
(0, -4), (0, 0), (0, 4).
m = (0 -(-4)) / (0-0)=4/0 = undefined.
Graph the line using the given points.
2. 5Y = 0
Y = 0 = A constant.
Since Y is constant,X is changing.
Therefore, we have a hor. line on
the X-axis and has a slope of 0:
(-3, 0), (0, 0), (3, 0).
m = (0 - 0) / (0 -(-3)) = 0 / 3 = 0.
Graph the line using the given points.
