Best ResponseYou've already chosen the best response.2Multiply the 3 by each term inside the matrix \[\large \color{red}{3*}\left[\begin{array}{cccc} 1 & 5 & 5 & 2\\ 2 & 5 & 3 & 4 \end{array}\right] = \left[\begin{array}{cccc} \color{red}{3*}(1) & \color{red}{3*}5 & \color{red}{3*}5 & \color{red}{3*}(2)\\ \color{red}{3*}2 & \color{red}{3*}5 & \color{red}{3*}3 & \color{red}{3*}(4) \end{array}\right] =??\] Note: the final result will be a 2x4 matrix

Best ResponseYou've already chosen the best response.2the first column 1, 2 turns into 3, 6 so it's the same as multiplying the point (1,2) by 3 to get (3,6). Dilating it out 3 times further away from the origin

Best ResponseYou've already chosen the best response.2each column of the matrix represents a point or ordered pair

Best ResponseYou've already chosen the best response.2eg: first column 1,2 means we have the point (1,2)

Best ResponseYou've already chosen the best response.2@jim_thompson5910 It's A?

Best ResponseYou've already chosen the best response.2Probably the best thing you can do is just graph each point. What I did was graph using geogebra. That program has a lot of interactivity and flexibility, which is why I like it So you'd graph each column as its own point eg: W = (1,2), X = (5,5), Y = (5,3), etc etc see the attached as for what you'd get in the graph
