Answer with explanation:
The equation of any line with slope 'm' and passing through any point
is given by

As we know that the general equation of a line with slope 'm' is 
Comparing with the given equation
we can conclude slope of the given line is 
Now we know that the product of slopes of perpendicular lines is -1
Mathematically we can write for perpendicular lines

Thus the slope of the required line is obtained from the above relation since it is given that they are perpendicular

Hence using the given and the obtained values the equation of the required line is

Part b)
The angle of intersection between 2 lines with slopes
is given by

Comparing the equations of given lines

with the standard equation we get

Thus the angle of intersection becomes

Answer:
I believe the answer is (-1,5)
Step-by-step explanation: because when you draw it out on a coordinate plain (-1,5) lies right in the middle of these two points.

Answer:
52 students were in each bus
Step-by-step explanation:
475-7=468÷9=52 so 52
Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area
