Answer:

10x + 5y = 11

Step-by-step explanation:

I usually find it in slope intercept then convert, it's easier for me.

First you find slope using delta y over delta x giving you -2/5.

so you have y=-2/5x + b

To find b plug in a point and solve down

1 = -2/5(3) +b

1+6/5 = b

b = 11/5

y=-2/5x + 11/5

Then you convert it to Ax+by=C form,

multiply by 5

5y = -10x + 11

move x

10x +5y = 11

What is the Inequality for this graph?

mote1985 [20]

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-0=\dfrac{-4-0}{0-6}(x-6)$

$y=\dfrac{-4}{-6}(x-6)$

$y=\dfrac{2}{3}(x-6)$

$y=\dfrac{2}{3}x-4$

The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.
