Parallel
write an equation parallel to y = 3/4(x) + 7
y = 3/4(x) - 5
write an equation perpendicular to y = -4/5(x) + 3
y = 5/4(x) + 2
What shape(s) has all equal sides?
square and rhombus
Are there congruent sides in AB = 4.2, BC = 7.7, CD = 4.2, and AD = 10.5
YES AB = CD
Is the line containing (4,1) and (6,-3) parallel to line y = 2x - 5
NOOOOOO -3 - 1 = -4 & 6- 4 = 2 Use the numbers. -4 / 2 = -2 -2 IS NOT = 2.
find the slope of the line containing points (-9,5) and (4,3), is the slope perpendicular to the line with equation y = 7x + 4
NO, -2/13 Is not Opposite reciprocal to 7/1
Given the following numbers of slope AB = 1/3, BC = -1/3, CD = -4/5, and AD = 4/5 , what shape could this be?
Kite
Find the mistake in the following distance problem A (4,7) and (9,-1)
SQrt (4 - 9) ^2 + (7 - - 1) ^2
SQrt (-5) ^2 + (8) ^2
SQrt -25 + 64
SQrt 39
NO negatives after square should be +25.
write an equation parallel to y = 1/3(x) + 6 and the line must go through (-2,15)
y = 1/3(x) + 47/3 or 15.67
Write an equation perpendicular to y = 3/2(x) + 6, that contains point (8,-3)
y = -2/3(x) + 7/3
Using slope and distance what shape could this be? explain.
AB = 2, BC = 5, CD = 2, AD = 5
slope
AB = 1/3, BC = -1/3, CD = 1/3, AD = -1/3
Parallelogram
2 sets //, NO O.R., and not all equal sides.
Find the distance of AB. A(0,10) and B = (3,2)
SQrt 73
AB is a line with slope 3/2. C is a point at (-2,1), what is a POSSIBLE point for D, that would make CD parallel to AB
(0,4) or (-4,-2)
AB is a line with slope -5/6, Point C is located at (0,4) Find the point D, where CD is perpendicular to line AB
Point D should be located at (5,10) or (-2,-5)
IF we know we have parallel sides but no equal distances, what we need to talk about to determine the figures shape? What 2 options do we have?
Rectangle if there are O.R.
Parallelogram is no O.R.
Find the distance of AB and CD are they congruent?
A(2,4) B(-3,6)
C(1,5) D(6,3)
YES both lines are distance of SQrt 29.
