2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal)
-5=-1/2(9) 9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5
Answer:
A its conistan when x less than 1 and x when x is larger
Answer:
tan 4x
Step-by-step explanation:
Note the difference identity for tangent ratio is
tan(x - y) = 
Given
← in the form of the right side of the expansion, thus
= tan(9x - 5x)
= tan 4x
