<h2>Finding the slope and y-intercept of a line given the graph</h2><h3>Answer:</h3>
An equation of a line written in its Slope-intercept Form, , has
as its
-intercept and
as its slope.
or the
-intercept is the
-coordinate when
. On the given line, we can see that when
,
. It's
-intercept is the point
so
.
The slope, , of the line can be calculated by
where
and
is the
-coordinates of any point
on the line. In the given line, we can see that
is on the line so this can be point
.
is also on the line (yes, you can also use the
-intercept in calculating the slope of the line) so this can be our point
.
The -intercept is
and the slope is
