Problema Solution
Find an equation for the line with the given properties. Express the equation in the slope-intercept form.
Containing the points P= (-5,4) and Q=(-3,1)
What is the equation of the line?
Answer provided by our tutors
the "slope-intercept" form of line is
y = mx + b
where "m" is the slope and "b" gives the y-intercept
m = (1 - 4)/(-3 - (-5))
m = -3/2
y = (-3/2)x + b
y = - 1.5x + b
the line contains P=(-5, 4) thus we have
4 = (-3/2)*(-5) + b
by solving we find:
b = -3.5

the equation of the line is:
y = (-3/2)x - 7/2
y = -1.5x - 3.5
