The domain is
and the range is
Domain is x values (horizontal axis), while range is y values (vertical axis). On a line like this one, domain is calculated from the left most point to the right most, while range is calculated from the down most to the upmost.
Because this line is a solid line rather than a dotted line, less than or equal to
signs are used rather than just
less than signs.
The points are; (7/2, -1/2).
<h3>What is the given point?</h3>
Now the tangent line is given as;20x 4y = 1. When we rewrite it in the slope intercept form, we have the equation as; y = 1 - 20x/4 or y = 1/4 - 5x.
Then to obtain the slope of the curve we have; y = 19 - 2x
dy/dx = 2
Using the relation;
m1m2 = -1
m2 = -1/2
Hence;
y = 1/4 - 5(-1/2)
y = 1/4 + 5/2
y = 7/2
Thus the points are; (7/2, -1/2)

Answer:
the answer is x<2
−2x+2>3x−8
Step 1: Subtract 3x from both sides.
−2x+2−3x>3x−8−3x
−5x+2>−8
Step 2: Subtract 2 from both sides.
−5x+2−2>−8−2
−5x>−10
Step 3: Divide both sides by -5.
−5x
−5

−10
−5
x<2
You can use zero as a starting point and then plot based on the direction of your number, so say you have a -1. You would plot that -1 to the left of 0 and any other negative numbers you have. Regarding positive numbers, they would all go to the right of zero so if you had to plot +1 you would plot that to the right of zero. I attached a photo to help you :)
