Answer:

The equation of the straight line in point-slope form

$y - 4 = \frac{7}{9} (x-0)$

The equation of the straight line

7x -9y +36 =0

Step-by-step explanation:

Step(i):-

Given that the points (0,4) and (-9,-3)

The slope of the line

$m = \frac{y_{2} - y_{1} }{x_{2}- x_{1} } = \frac{-3-4}{-9-0} = \frac{7}{9}$

Step(ii):-

Equation of the straight line passing through the point (0,4) and having slope m = 7/9

$y - y_{1} = m (x-x_{1} )$

$y - 4 = \frac{7}{9} (x-0)$

9 y - 36 = 7x

9y = 7x + 36

$y = \frac{7x}{9} +\frac{36}{9}$

Slope - intercept form

$y = \frac{7x}{9} +4$

Final answer:-

The equation of the straight line in point-slope form

$y - 4 = \frac{7}{9} (x-0)$

The equation of the straight line

7x -9y +36 =0

A 16 ft board is to be cut into three pieces, two equal-length ones and the third 3 in. shorter than each of the other two. If

Dahasolnce [82]

Answer:

The first two pieces are 5' 5" long; the last piece is 5' 2" long.

Step-by-step explanation:

If x is the length of one of the longer pieces, then the shorter one (in inches) is x-3. The total length of the three pieces is ...

x + x + (x-3) = 192

3x = 195 . . . . . . . . . add 3

x = 65 . . . . . . . . . . inches

65 inches = 5 ft 5 inches

The first two pieces are each 5' 5" long; the remaining piece is 5' 2" long.
