Y = -1/3x + 2.....the slope here is -1/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the slope and change the sign. So the slope is -1/3.....flip it and it becomes - 3/1....change the sign and it becomes 3/1 or just 3. So ur perpendicular line will have a slope of 3.
y = mx + b slope(m) = 3 (-3,-5)....x = -3 and y = -5 now sub into the formula and find b, the y int -5 = 3(-3) + b -5 = -9 + b -5 + 9 = b 4 = b so ur perpendicular equation is : y = 3x + 4 <===
1. Is angle 2 and angle 5 are supplementary and the reason is the given 4. The answer is L || M because of the converse of the CIA theorem( corresponding interior angles)
