 Slope, SlopeIntercept, Standard Form,
a selection of answers from the Dr. Math archives.
 For an introduction to The Coordinate Plane
and Lines and Slope, see Ursula Whitcher's units on
Chameleon Graphing at the Math Forum site.
 Slope
 What is Slope?
 What is a slope, and if given a slope = n equation, how do you
apply that slope number to another graph problem?
 Slope Angle
 What units do we use to refer to slope?
 Determining Slope
 How do I find the slope of a line given the coordinates of two
points?
 Drawing a Line, Given the
Slope and One Point
 How do I draw a line on a graph when I know the slope and the
location of only one point on the line?
 Graphing Coordinates
 How can you tell if you have a straight line just by looking
at the numbers?
 Slope of Lines
 What is the slope of the line y = px + 5 if the line goes through
(0,3)? Why does the yaxis have an infinite slope, and the xaxis have
a slope of 0?
 Slopes of Perpendicular Lines
 Why are the slopes of perpendicular lines negative reciprocals?
 SlopeIntercept
 Equation in Slope Intercept
or Point Slope Form
 Find an equation of the line with slope 4/3 and yintercept 3.
Leave the equation in slope intercept form....
 Write in SlopeIntercept Form
 Write and sketch x  y + 2 = 0.
 Equation of a Line Parallel
to an Axis
 How can I get the equation of a line if the line passes through a
point and is parallel to the x or yaxis?
 Finding the Equation of a Line
 Given either a point and a slope or two points, how do you find the
equation of a line in both pointslope and standard form?
 How to Draw Linear Equations
 How would I draw the line y = (2/3)x + 5?
 Graphing Linear Equations
 How do I find the points on the line so that I can find the slope
and the yintercept?
 Equation of a Line in
PointSlope, SlopeIntercept, General Form
 What is the equation of the line that contains the point (4, 4)
and is perpendicular to the line defined by 2x5y+3 = 0?
 Equation of a Line
 How do I find the equation of a line through the origin perpendicular
to 2x + 3y = 5?
 Changing Equations To SlopeIntercept
Form
 Can you explain how to change equations into slopeintercept form?
For example, 12(2x1)  5(3y+2) = 8?
 When is a Slope 0 or Undefined?
 How do I know when the slope of an equation is zero or undefined
(no slope)?
 Undefined Slope and Zero Slope
 What is the difference between an undefined slope and a slope of zero?
 Finding yintercepts
 I'm having a problem with finding and graphing yintercepts of linear
equations.
 Equations of a Line given Two Points
 How do you find the equation of a line going through two points
if you only know the two points?
 SlopeIntercept Formula
 Why does y = mx + b have to be that way?
 Graphing y = mx + b
 After you get 3 x+ 2y = 5 into y = mx + b form, how do you graph it?
 Graphing Intercepts
 How would I find the intercept for a problem such as 3x2y = 12?
 Standard Form of a Line
 What is standard form? What does Ax+by = c mean and what do the
letters stand for?
 Linear Equations and Standard Form
 What do the variables mean in the standard form of a linear equation
(ax+by=c)?
