Slope Equations of Lines Parallel and Perpendicular Lines Etc

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 the line, determine the B value of the line below. 4x + By = -10 B = -2

Identify the slope of the line 3x – 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 the point (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)

A line has a slope of. It contains the points A(2,5) and B(-1,y). Identify the y-coordinate of point B. y = 3

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 line that 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 line 4x – 3y = 15 containing the point (8, 1). The equation should be written in point-slope form. y – 1 = (-3/4)(x – 8)
