Today you will
write linear equations in
slope-intercept form,
point-slope form, and
standard form.
Write an equation of the line in slope-intercept
form for the following conditions:
slope = 1
4
and passes through the point (6, -3)
Write an equation of the line in slope-intercept
form for the following conditions:
slope = -3
5
and passes through (10, 0)
Write an equation of the line in slope-intercept
form for the following conditions:
slope = 0
and passes through (4, -7)
When you know the slope and a point on
a line, you can also write an equation for
the line in point-slope form.
If the point (x1 , y1 ) lies on a line with slope m,
y - y1 = m(x - x 1 )
Write an equation in point-slope form for the line that
has the given slope and passes through the given point.
m = 3
point (5, 4)
m = 3
point (-5, -4)
Write an equation in point-slope form of the
line that passes through (1, 6) and (3, -4)
Now write it in slope-intercept form:
Now write it in standard form:
