How do I write an equation if there is a fraction involved?
A line with slope 3/2 that passes through the point (-2,0)
Thanks very much!!
Favorite Answer
y = slope * x + y-intercept
y = (3/2)x + 3
another way to write it is
y = (3x / 2) + 3
why I answered how to do it
with your last question
use the pt slope formula
you have been given one point
that means the other point is
(x,y). consider the point given
(-2,0) to be your start point, and (x,y)
your end point. from the last lesson
y(end)-y(start)=M(x(end)-x(start))
M is slope.
do the substitutions and simplify
to reach the eqn you need.
I believe your next question should
be about finding the end point, so I will tell
you how to do that
M=rise/run
rise=change in height (change in y values)
run=change in distance(change in x values)
M=(y(end)-y(start))/(x(end)-x(start))
for the information you gave in
this problem
M=3/2 and that means
this ratio means y changes by 3
and x changes by 2
as the line goes through space
y(end)-y(start)=y(end)-0=3
thus y(end)=3……(x,3)
x(end)-x(start)=x(end)-(-2)=2
thus, x(end)=0……(0,y)
the point is then
(0,3) the zero in the x position
also tells us that 3 is the y-intercept.
y-intercept is where the line passes through
the y-axis and that only happens when
x=0.
