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.
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).
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
The formula for a line is: Y = mX + b
y=-2x+3
Because if you ever want to graph that equation you need the actual equation itself to help you graph it.
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
-12
The equation of a line with an undefined slope is x = a.
The equation for a line is y = mx + b, where m is the slope and b is the y-intercept.
I need step by step on my graphic calculator on how to write an equation
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 (3, -5) and (-4, -5)

Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
A vertical line has the equation [ x = a number ]. A horizontal line has the equation [ y = a number ].
y = ax + b
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
