Comment: A METHOD is better than an answer.
-----------
Find the x-intercept of the line.
METHOD: To find the x-intercept, let y = 0; then solve for x, as follows:
1.x-2y=4
x-0 = 4
x = 4
-----------
2.2x-3y=6
2x -0 = 6
x = 3
---------------
etc.
3.-6x-4y=42
4.-x-5y=12
5.-13x-y=39
===================
Find the y-intercept of the line.
METHOD: To find the y-intercept, let x=0; then solve for y, as follows:
6.y=-3x+7
y = 0+7
y = 7
------------
7.y=6x-24
y = 0-24
y = -24
-------------
etc.
8.2x-17y--51

I'll do two of each to give you examples to work with
# 1
x-intercept
The x-intercept occurs when (graphically this is on the x-axis).
So 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.
So the x-intercept is )
. Note: the x-intercept is in the form (some number, 0)
=====================================================
# 2
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 )
.
=====================================================
# 6
y-intercept
The y-intercept occurs when (notice how the opposite is the case for the x-intercept).
So to find the y-intercept, plug in and solve for y
Start with the given equation.
Plug in .
Multiply and to get .
Combine like terms.
So the y-intercept is )
. Note: the y-intercept is in the form (0, some number)
=====================================================
# 7
Start with the given equation.
Plug in .
Multiply and to get .
Combine like terms.
So the y-intercept is )
.
Note: you can see if the equation is in the form , then the y-intercept is simply (0,b). So we can avoid the work in problems #6, and #7 by just looking at the last value.
