Hi
1. What is the equation of a line that passes through points (-1, 2) and (5, 2) y = 2
7. What is the equation of a line with a point (-3, 0) and no slope? x = -3
*[tex \LARGE\ Using \ the \ standard \ slope-intercept \ form \ for \ an \ equation \ of \ a  \ line \ y = mx + b ]
*[tex \LARGE\ where \ m \ is \ the \ slope \ and \ b \ the \ y-intercept]
2. What is the equation of a line with a slope of -2 and a y-intercept of 8?
y = -2x + 8
3. What is the slope of a line parallel to the line whose equation is y - x = 5?
y = x+ 5   parallel lines have equal slopes of m = 1
4. What is the equation of the line that passes through the point (1, 1) and has a y-intercept of 2.
y = mx + 2
1 = m + 2    m = -1
y = -x + 2
5. The slope of a line is 1/3 . What is the slope of a line perpendicular to this line?
&#8869; Lines have slopes that are negative reciprocals of one another:  m = - 3/1
6. What is the slope of a line perpendicular to the line whose equation is y = 2x + 5?  m =  -1/2
8. What is the equation of a line that passes through point (1, -2) and has a slope of 1/3 .
y = (1/3)x + b
-2 = 1/3 + b
-7/3 = b
y = (1/3)x -7/3
