Step-by-step explanation:
<u>Graph of an inequality</u>
The graph represented in the image is a line and we have two clear points through which the line passes.
Those points are (0,1) and (5,0).
The equation of a line can have the slope-intercept form:
y=mx+b
Substituting the point (0,1):
1=0+b
b=1
Substituting the point (5,0):
0=m(5)+1
Solving for m:
The equation of the line is:
The origin belongs to the solution if we substitute (0,0) the inequality should stand:
0<1
Or:
0≤1
Since the line is dashed, the boundary line is not part of the solution
Thus the inequality is:
Option D.
C(3)=Ishann's age
Ishann is 14 years older than Christopher
7*3=21-7=14
So Christopher is 7 years old
Given:
A line passes through the points (-1, -1) and (5,8).
To find:
Which points lie on the same line?
Solution:
If a line passes through two points, then the equation of the line is:
A line passes through the points (-1, -1) and (5,8). So, the equation of the line is:
Multiply both sides by 2.
So, the equation of the line is .
Now, check each point for this equation.
Putting 
, we get
Similarly,
For

For 
.
Therefore, the points (-3,-4), (9,14), (1,2) and (3,5) lie on the same line but the points (4,7) and (-2,-2) are not on that line.
