Answer: The required answers are
(a) the slope of the given line is
(b) y-intercept exists and is equal to 6.
(c) the slope-intercept form of the line is
Step-by-step explanation: We are given the following linear equation in two variables :
We are to :
(a) determine the slope,
(b) determine the y-intercept, if exists
and
(c) express equation in slope-intercept form.
We know that
The SLOPE_INTERCEPT form of the equation of a straight line is given by
where m is the slope and c is the y-intercept of the line.
From equation (i), we have
Comparing with the slope-intercept form, we get
Thus,
(a) the slope of the given line is
(b) y-intercept exists and is equal to 6.
(c) the slope-intercept form of the line is
Answer:
Step-by-step explanation:
(-6 , 4) & (-1 , 2)
Slope =
m = -2/5 & (-6 , 4)
y -y1 = m(x -x1)
