There are several ways to write an equation for a line. One common form is ax + by = c, where a, b, and c are some constant values. A very useful form of the line equation is y = mx + b (m and b are constant). Since this is solved for "y", you can easily calculate pairs of value. Besides, m is the slope, and b is the point where the line intercepts the y-axis. This form can't be used to describe a vertical line, though.

Can you always write the equation of a line if you know one point on the line?
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
How do you write an equation with and undefined slope?
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
Write the equation of the line passing through points?
The formula for a line is: Y = mX + b
Write an equation of a line with a negative slope?
y=-2x+3
Why is knowing how to write an equation of a line important?
Because if you ever want to graph that equation you need the actual equation itself to help you graph it.
How do write an equation of a line when given the slope a point of the line?
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Write the equation of the line that has a slope of -8 and a y-intercept of 4?
-12
Write an equation for undefined slope?
The equation of a line with an undefined slope is x = a.
How do you write the equation of a line?
The equation for a line is y = mx + b, where m is the slope and b is the y-intercept.
Write an equation in standard form of the line satisfying the following condition the line through -55 and is horizonal?
I need step by step on my graphic calculator on how to write an equation
Can you write the equation of a line with one point on the line?
No, you need either two points, one point and a slope, one point and a y-intercept, or a y-intercept an a slope. You can also write the equation of a line with an equation of another line but you would have to know if it is parallel or perpendicular.
Write the equation of the line that passes through the points 12 and 6 and 12 and -4?
Write the equation of the line that passes through the points (3, -5) and (-4, -5)
Can you always write the equation of a line if you know one point on the line?
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
How do you write equations for ertical and horizontal lines?
A vertical line has the equation [ x = a number ]. A horizontal line has the equation [ y = a number ].
How do you write an equation with and undefined slope?
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
Write an equation for a line graph.?
y = ax + b
Write in slope intercept form the equation of the line that is parallel to the given line and passes through the given point?
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
