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

Write an equation in point-slope form and slope-intercept form for each line: Passes through (3,-6) and (-1,2)

ratelena [41]

Slope intercept form is y=m(x)+b
M is the slope to find it you do the first y value minus the second y value and do the same for x
-6-2. 3+1
You then divide the subtracted y values by the subtracted x values
-8/4
M=-2
To find the b you plug in one set of the coordinates
-6=-2(3)+b
-6=-6+b
b=0
So the equation is
Y=-2x

Find three positive consecutive integers such that the product of the second integer and the third integer is 72

Anastaziya [24]

Let
x---------> first positive integer
x+1------> second positive integer
x+2-----> third positive integer

we know that
(x+1)*(x+2)=72-------> x² +2x+x+2=72 -------> x² +3x-70=0

using a graph tool-------> <span>I solve the quadratic equation
</span>see the attached figure

the roots are
x1=-10
x2=7

the answer is
first positive integer is x=7
second positive integer is x+1=8
third positive integer is x+2=9
