Answer:

see below for the working

Step-by-step explanation:

Dividing by a number is the same as multiplying by the inverse of that number.

$\displaystyle\frac{\left(\frac{1}{4}\right)}{\left(-\frac{2}{3}\right)}=-\frac{1}{4}\cdot\frac{3}{2}=-\frac{3}{4\cdot 2}=-\frac{3}{8}$

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 3) and (2, negative 1). Everything to th

Answer:

The answer to your question is y < -2x + 3

Step-by-step explanation:

See the graph below

Process

1.- Find the slope

$m = \frac{y2 - y1}{x2 - x1}$

Substitution

$m = \frac{-1 - 3}{2 - 0}$

$m = \frac{-4}{2}$

$m = -2$

2.- Find the equation of the line

y - y1 = m(x - x1)

Substitution

y - 3 = -2(x - 0)

Simplify and solve for y

y - 3 = -2x

y = -2x + 3

3.- Write the inequality

As the left area of the plane is shaded the inequality must be

y < -2x + 3

Write the equation of the line with a slope of 2 that contains the point (3, 9) .

mr Goodwill [35]

Answer:

Step-by-step explanation:Here the slope of the line = m = 2

The line passes through the point ( x 1 , y 1 ) = ( , 9 ).

The equation of the line with slope m and passing through the point ( x 1 , y 1 ) is given by ( y - y 1 ) = m ( x - x 1 )

( y - 9 ) = 2 ( x - 3 )y - 9 = 2 x - 6

Collecting terms in one side

0 = 2 x - y - 6 + 9

2 x - y + 3 = 0
