Hello:
I am doing a math worksheet that I was given by my teacher, the sheet is full of slope problems. y = mx + b. You are given two points:
Example:
(4,1) (5,3) and you have to find what Y = and my answer was Y = 2x - 7
------------------------------
There are two equations on here where it says X = for the answer instead. The two points are (4,1) and (4,13).
Hopefully I am not being too confusing, thanks in advance for any help.
and are on the line .
You may sketch these two points in a coordinate system and construct a line through them, and as it can be seen this line is actually perpendicular to the x-axis.
That means, all points designated as (4, a) (a can be any real number) are on the line because they all satisfy the condition that x = 4, given that there is nothing required for y.
