Triangle ABC has vertices A(−3,−1), B(−4,3), C(1,2). a) Graph Triangle ABC.
b) Reflect the quadrilateral in the line y=x.

c) Then, find the image of A′′B′′C′′ after a dilation with its center at the origin and a scale factor of 2.

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
