1. For any type of data a line graph and bar work but sense u are comparing a double line graph is best
There are 2 triangles that exist within this single triangle. It is an SSA triangle, so it is the case of the ambiguous triangle. Sounds scary. You have to drop an altitude and find out what the height of it is. You can use the sin45 = h/5 to find that the height is 3.5. The rule for this is if the height is smaller than b and b is smaller than c, you have 2 triangles. That is true here, so you have 2 triangles. Solving both of them involves the Law of Sines and the rules of supplementary angles...a whole 'nother type of pain in the butt.
Q' = (7, 2 ) and R' = (1, - 5 )
given P(- 4, 4 ) and P'(3, 1 ), then the translation vector is
v = < 3, 1 > - < - 4, 4 > = < 7, - 3 >
Thus to obtain the coordinates of the images, add 7 to the x-coordinate and subtract 3 from the y-coordinate
Q(0, 5 ) → Q'(0 + 7, 5 - 3 ) → Q'(7, 2 )
R(- 6, - 2 ) → R'(- 6 + 7, - 2 - 3 ) → R'(1, - 5 )
