How do you graph a linear inequality in two variables

Mathematics

FrozenT [24]3 years ago

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.
Example:

Is (1, 2) a solution to the inequality
2x+3y>1
2times1+3times2>1
2+5>1
7>1

Find the distance between A(4,8) B(1,12)
Effectus [21]

From the formula:

Distance = Sq Root [(X2 -X1)^2 + (Y2 -Y1)^2]

Distance = Sq Root [(1 -4)^2 + (12 -8)^2

Distance = Sq Root [-3^2 + 4^2]

Distance = Sq Root [9 + 16]

Distance = 5

<h3>Answer:</h3>

18

<h3>Solution:</h3>
  • First, evaluate 2^3, which equals 8.
  • Next, evaluate 4^2, which equals 16.
  • This is the simplified expression:
  • 3/4(8+16)
  • 3/4(24)
  • Multiply:

I sold 32 posters for a total of 126. And I sold 48 posters for a total of 240. If the relationship between the number of poster
Oksanka [162]

Answer:

The cost per print expressed as a slope is 7.125

Step-by-step explanation:

To calculate the cost per print, let’s envision that we have a graphical representation of cost of posters against the number of posters

We have the cost on the y-axis and the number of posters on the x axis

With the information given in the question, we shall be having two data points

Point 1 = (32,126)

point 2 = (48,240)

Now to find the slope of the line which is cost per print, we make use of both points in the slope equation.

Mathematically, slope m will be

m = y2-y1/x2-x1

Thus, we have;

m = (240-126)/(48-32)

m = 114/16

m = 7.125

The cost per print expressed as a slope is 7.125
