A. the point-slope form of the equation of a line is y ? y1 = m(x ? x1), where m is the slope and (x1, y1) is a point on the line. write the equation of the line in point-slope form perpendicular to the graph of y = 1/2x -7 passing through the point (6, 5).

b. write an equation of the perpendicular bisector of jk, where j = (? 8, 4) and k = (4, 4).

can you show work .

A.

Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.

Then apply point-slope form.

B. The answer is x = 6.

The midpoint of JK is

The line that goes through JK is just a horizontal line because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is, .

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
