scoray [572]3 years ago
7 0

Answer:

y=-3x+4

Step-by-step explanation:

The y intercept is 4 because the line crosses the y axis at the 4 tic mark

The slope will be -3 because the y decreases by 3 every time the x incerases by 1

y=mx+b

y=-3x+4

A walking path across a park is represented by the equation y=-3x - 3.A
kifflom [539]

Answer:

  y -6 = 1/3(x +3)   or   y = 1/3x +7

Step-by-step explanation:

The slope of the line describing the given path is the x-coefficient, -3. The slope of the perpendicular line will be the negative reciprocal of that:

  m = -1/(-3) = 1/3

The point-slope form of the equation for a line can be used to write the equation for the new path:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For m=1/3 and (h, k) = (-3, 6), the new path can be represented by ...

  y -6 = 1/3(x +3) . . . . point-slope form

  y = (1/3)x +7 . . . . . . slope-intercept form

Anna007 [38]

Answer:

336 ft²

Step-by-step explanation:

The rectangle is   13  ft long  and  8 width  that means we have  two walls 8* 9   and  two walls  13*9

Total walls area is

2*8*9 + 2*13*9   =   144  + 234   =  378 ft²

then we subtrac  , areas of door, closet and windows

3 * 6.5  =  19,5 ft²

3 * 6,5  =  19,5 ft²

2 * 1,5   =   3   ft²

               42 ft²

Then area to paint    378  -  42   =  336 ft²
