What is a slope?
|
The ratio of the "rise" divided by the "run" between two points on a line
|
The slope m is the line of m=y2-y1/x2-x1. The formula fails for a vertical line, parallel to the y axis, where the slope can be taken as infinite, so the slope of a vertical line is considered undefined.
|
|
|
What is slope-intercept form?
|
y=mx+b is the slope intercept form. where m is the slope of the line and b is the y-intercept, which is the y-coordinate of the location where line crosses the y axis.
|
the point (0,2) has a slope intercept form of y=1x+2
|
|
|
What is standard form?
|
Standard form is Ax+By=C where A and B are not both equal to zero. A, B, and C are co-prime integers, and A is non-negative. Iif zero, B must be positive
|
The standarm form of y=3x+2 is y-3x=2
|
|
|
What is a horizontal line?
|
A straight line that goes left to right.
|
The points (0,1) (0,2) and (0,3) would create a horizontal line.
|
|
|
What is a vertical line?
|
A vertical line is a straight line that goes from bottom and continues up.
|
The points (0,1),(0,2) and (0,3) would make a vertical line.
