Answer:
(-3,-1)
Step-by-step explanation:
6 7/8 -> 55/8 /5= 11/8*6= 66/8 /2 = 33/4
Answer:
-10
Step-by-step explanation:
Substitute 5 into the equation
(-5)2
Simplify and get -10
Y = 1/3x ? 6....slope here is 1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3 (see how I flipped 1/3 and changed the sign)
y = mx + b
slope(m) = -3
(-9,12)...x = -9 and y = 12
now we sub and find b, the y int
12 = -3(-9) + b
12 = 27 + b
12 - 27 = b
-15 = b
so ur perpendicular equation is : y = -3x - 15
