Use the intercepts to graph the equation 4x-2y=8 please help me solve and graph

Step 1. For this example, y-intercept is when x=0 and

So one point is (0,-4).

Step 2. For this example, x-intercept is when y=0 and

So the other point is (2,0).

The following will graph the equation using the two points:

Note the x-intercept at point (2,0) and y-intercept at point (0,-4)

I hope the above steps were helpful.

x-intercept

To find the x-intercept, plug in and solve for x

Start with the given equation.

Plug in .

Multiply and 0 to get 0.

Simplify.

Divide both sides by to isolate .

Reduce.

So the x-intercept is .

------------------------------------------

y-intercept

To find the y-intercept, plug in and solve for y

Start with the given equation.

Plug in .

Multiply and 0 to get 0.

Simplify.

Divide both sides by to isolate .

Reduce.

So the y-intercept is .

Now plot the points

and draw a straight line through them to graph the equation

Graph of

use the intercepts to graph the equation 4x-2y=8 please help me solve and graph
--------------
To use the intercepts, set x=0 and find y
0-2y = 8
y = -4 --> (0,-4)
-------------
Set y = 0 and find x
4x = 8
x = 2 --> (2,0)
-----------
Draw a straight line thru the 2 points.
