Is (-1,2) a solution of y=-5x+7
2 answers:
Gotcha!
When graphing this equation, (-1,2) does NOT cross on the graph. If you're are look for "m", the answer would be -5. So no, (-1,2) is not a solution to y=-5x+7.
:-)
No, it is not. I will show you:
-1 = x and 2 = y
2 = -5(-1) + 7
2 is not equal to 12. I hope this is right!

Recall: SOHCAHTOA
Sin M = Opp/Hyp
Reference angle = M
Opp = 3√/21
Hyp = 15
Sin M = (3-√21)/15
Sin M = √21/5
Cos M = Adj/Hyp
Reference angle = M
Adj = 6
Hyp = 15
Cos M = 6/15
Cos M = 2/5
Tan M = Opp/Adj
Reference angle = M
Opp = 3√21
Adj = 6
Tan M = (3√21)/6
Tan M = √21/2
:Therefore: Sin M = √21/5
Cos M = 2/5
Tan M = √21/2
