which ordered pair is the solution to this equation? -2x+9y=-26 a.(-4,-4) b.(4,4) c.(-4,-5) d.(-5,-4)
here is the graph of the line
okhay whats the answer?
well none of thoses are on the line so are you sure you typed the answers right? if you did then i think there is a typo
thats it... thats how it was
Try d. -2(-5) + 9(-4) =10-36=-26 Looks like it would work.
radar got the right answer, d. A solution using Mathematica with comments is attached.
Interesting pdf. I like the fact it checked the wrong answers also producing false outputs.
radar, Thank you.
