Find the slope of the line that contains the points(-1, 9) and (4, 5).
m = - 4/5
Write the equation of a line with a slope of 3 containing the
point (0,-7). Write the equation in slope-intercept form.
y = 3x - 7
Identify the slope of every line parallel to the line
4x – 6y = 18.
m = 2/3
Determine whether the point is on the line. Show work to
support your answer.
-5x + 3y = -8; (2,6)
NO!!
What is the slope of a horizontal line?
m = 0
y – 5 = - 4(x + 1)
Write the equation of a line with a slope of -4 containing the point
(-1, 5). Write the equation in point-slope form.
Identify the slope of every line perpendicular to the line
y – 6 = 3(x + 1).
m = -(1/3)
Given the point (2, 9) is on theline, determine the B value
of the line below.4x + By = -10
B = -2
Identify the slope of the line3x – 4y = 20.
m = 3/4
Write the equation of any horizontal line.
Answers will vary. The equation must be in the form y = ___.
Write the equation of the line parallel to the line
3x – 6y = 30 containing thepoint (2, -7). The equation should be written in slope-intercept form.
y =(1/2)x - 8
Identify the coordinates of the x-intercept of the line below.
5x + 2y = -30
(-6, 0)

Write the equation of the vertical line that contains the
point (-7, 2).
x = -7
Write the equation of the line parallel to the line y = 3
containing the point (-1, -5).
y = -5
Write the equation of the line (in slope-intercept form)
perpendicular to the line y = x passing through the origin.
y = -x
Identify the slope of the line that contains the points (-3,6) and (-3,-1)
The slope of a vertical line is undefined!
Write the equation of the linethat contains the points
(-4,7) and (5,1). The equation should be written
in point-slope form.
y – 7 = (-2/3)(x + 4) or y – 1 = (-2/3)(x – 5)
Write the equation of the line perpendicular to the line4x – 3y = 15 containing
the point (8, 1). The equation should be written in
point-slope form.
y – 1 = (-3/4)(x – 8)
