the equation of line cd is (y−3) = − 2 (x − 4). what is the slope of a line perpendicular to line cd?
line cd contains points a (4, 6) and b (−2, 6). the slope of line cd is
line qr contains (2, 8) and (3, 10) line st contains points (0, 6) and (−2, 2). lines qr and st are
the equation of line qr is y = negative 1 over 2x + 1. write an equation of a line perpendicular to line qr in slope-intercept form that contains point (5, 6).
the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5).
line qr contains (2, 8) and (3, 10) line st contains points (0, 6) and (−2, 2). lines qr and st are
parallel because the product of the slopes is −1
perpendicular because the product of the slopes is −1
parallel because the slopes are the same
perpendicular because the slopes are the same

question 4
(06.02 mc)
the equation of line qr is y = negative 1 over 2x + 1. write an equation of a line perpendicular to line qr in slope-intercept form that contains point (5, 6).
y = 2x + 16
y = negative 1 over 2x + 17 over 2
y = − 1 over 2x + 7 over 2
y = 2x − 4
question 5
(06.02 mc)
the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5).
y = −2x + 13
y = negative 1 over 2x + 7
y = 1 over 2x + 3
y = − 2x − 3
