You need to draw out the slope on a piece of graph paper and u can figure it out
we have
------> inequality A
The inequality A is the solid red line in the graph
the solution of the inequality A is the shaded area above the solid red line
------> inequality B
The inequality B is the solid blue line in the graph
the solution of the inequality B is the shaded area above the solid blue line
we know that
the point lie on the line of the inequality B
substitute the values of x and y in the equation of the line
so
the equation of the line B is
the equation of the inequality B is
therefore
<u>the answer is</u>
The number is
It belongs to rational numbers, hope this helps!

Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
