How do you graph #x-2y=1# using intercepts?

Answer 1

Eva Abramson

using the intercepts of (1,0) and (-0.5,0)

substitute y=0. x=1 Therefore (1,0) is the x-intercept of the equation

substitute x=0. -2y=1 y=-0.5 Therefore (0,-0.5) is the y-intercept of the equation.

By plotting both points on the graph and linking them together, you have: graph{x-2y=1 [-10, 10, -5, 5]}

with the two intercepts.

To graph (x - 2y = 1) using intercepts:

Find the x-intercept by setting (y = 0) and solving for (x): (x - 2(0) = 1).
Solve for (x): (x = 1).
Plot the point (1, 0) on the x-axis.
Find the y-intercept by setting (x = 0) and solving for (y): (0 - 2y = 1).
Solve for (y): (y = -\frac{1}{2}).
Plot the point (0, -0.5) on the y-axis.
Draw a straight line passing through both intercept points to complete the graph.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
