Graphing an inequality is when you shade in the graph based on whether your point that you chose(usually (0, 0))  is true or false when put back in the original equation.

Graphing an equation of a line is just a line on the graph.

For a solid line: the inequality should be greater then or equal to or less then or equal to.

For a dashed line: the inequality should just be greater then or less than.

Hope this helps for your inequality equations :)

Find an equation of the line perpendicular to y = -1/2x – 3 that crosses the point
alisha [4.7K]

Answer:

<em>y = 2x + 4 </em>

Step-by-step explanation:

y = - \frac{1}{2} x - 3

Slope of perpendicular line is "2"

( - 3 , - 2 )

y + 2 = 2( x + 3 )

<em>y = 2x + 4</em>

What would the graph of 10x + 7y &lt; 49 look ?
navik [9.2K]

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

10x+7y

2. The equation of the line in slope intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

y=-\frac{10}{7}x+7

then:

m=-\frac{10}{7}\\\\b=7

4. Find the x-intercept. Make y=0. Then:

0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.
