How to calculate part b and c of this question? ?

For part a, while you didn't ask about this particular part, the equation you should have found is .\

For part b, we are given that ∠M = 90°. Recall that perpendicular lines join at a right angle by definition, and that the slope of a perpendicular line is the negative reciprocal slope
.
Using the slope from part a, , so .
We can write the equation of the line through M and N as .
We are trying to fine the value p for which x is 16, so we substitute 16 into the equation we just found and solve for y (which is p).



For part c, .

Your answer should be “b” i truly hope i could ! good luck (:

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
