Answer:
The graph of given equality is shown below.
Step-by-step explanation:
The slope intercept form of a line is
.... (1)
where, m is slope and b is y-intercept.
The given inequality is
The related equation of the given inequality is
.... (2)
On comparing (1) and (2), we get
It means the slope of the line is -3 and y-intercept is 1. The graph of related line is a solid line because the sign of inequality is ≥.
Check the given inequality by (0,0).
This statement is false. So, (0,0) is not included in the solution set.
Therefore, the graph of given equality is shown below.

Answer:
An equation relating x and y is:
y = 3/4x - 5.5
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
Given the points
(2, -4), (x, y), A(6, -1), and B(10, 2)
Taking any two points let say A(6, -1), and B(10, 2) to determine the slope
Refine
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -5.5
Thus, the y-intercept b = -5.5
Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation
y = mx+b
y = 3/4x + (-5.5)
y = 3/4x - 5.5
Therefore, an equation relating x and y is:
y = 3/4x - 5.5
