math help regarding point-slope equations

[mike93]

I need to write an equation in point-slope with the following info:

1.containing (-2,3) and parellel to x=1

2.containing (-1,-6) and parellel to y=-1

I know I must use the equation: y-y1=m(x-x1). But how do I complete the equation when the slope is 1?

1(x - x1) = x - x1

I need to write an equation in point-slope with the following info:

1.containing (-2,3) and parellel to x=1

Anyline parallel to x = 1 will have an equation as follows:

x = constant

Now if the line must pass through (-2,3) - what would that constant be?

To clarify, sketch the problem on a graph paper.


2.containing (-1,-6) and parellel to y=-1

Write y =-1 in the form of y = mx + b

What is the 'm' for line y = -1

I know I must use the equation: y-y1=m(x-x1). But how do I complete the equation when the slope is 1? << for these two problems - neither of these have slope = 1
