Saw the system of two linear inequalities graphically. Graph the solution set of the first linear inequality. Choose the type of
boundary line? Find the two points on the boundary line? Select the region to be shaded?
1 answer:
dashed
(-4, 0) and (0, -10)
region B will be shaded
Explanation:
We are asked to graph the 1st solution set which is:
The inequality doesnot have an equal sign attached to it. So, the line will be dashed
Plottimg the graph of the inequality:
The two points on the boundary will fall in the shaded part of the graph.
We can pick any two points on the dased line:
(-4, 0) and (0, -10)
The shaded part in our graph of the inequality corresponds to B in the question
Hence, region B will be shaded

Answer:
Step-by-step explanation:
Hi there!
Slope intercept form: where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Find the slope (m)</u>
where the two given points are
and
Plug in the given points (2,8),and (8,2)
Therefore, the slope of the line is -1. Plug this into :
<u>2) Find the y-intercept (b)</u>
Plug in a given point and solve for b
Add 2 to both sides
Therefore, the y-intercept is 10. Plug this back into :
I hope this helps!
