The perpendicular slope would be the negative reciprocal of -3, which is .
Let's see what the y-intercept should be, by finding one third of -6 and seeing how much we need to add or subtract to reach -9.
1/3 times -9 is -3.
To reach -6, we need to subtract 3.
So, the y-intercept is 7.
The equation is: .
Answer:
-5
Step-by-step explanation:
Answer:
Points P, Q and R are collinear
Step-by-step explanation:
To prove that two or three points are collinear the slope of any two pairs of point have to be the same
From the given question
AR = AQ = CP = 2 units
BR = BP = CQ = 1 unit
For line AB we have ; AR , BR . hence slope of line = BR / AR = 1/2
For line BC we have ; BP , CP . hence slope of line = CP / BP = 2/1
For Line AC we have ; AQ , CQ . hence slope of line = CQ / AQ = 1/2
slope of Line AB = slope of Line AC hence points P, Q and R are collinear
Distance covered in 1 week which involves 3 days of walking to the library = 0.83 miles
In 4 weeks,
Total distance walked = 4*Distance covered in 1 week = 4*0.83 = 3.32 miles.
The correct answer is B. since the distance walked ≥ 3.32 miles and not too large than 3.32 miles.
Answer:
1.8 km
Step-by-step explanation:
54 km/hr
54/60 = 0.9 km/min
In 2 mins:
0.9 × 2 = 1.8 km
