D. x is greater than or equal to -8
Explanation:
The inequality given by the problem is:
In order to solve it, we must do the following steps:
- Multiply by 4 on both sides of the inequality:
- Change the sign of both sides: when doing this step, we must reverse the sign of the inequality:
So, the correct option is
D. x is greater than or equal to -8
Answer:
y = -1/2x - 1
Step-by-step explanation:
Given equation:
y = 2x - 3
Given point: (x1,y1) = (-8,3)
This is in the form of y = mx + c,
so, m1 = 2
If the lines are perpendicular then the product of their slope will be - 1 i.e.
m1 x m2 = -1
2 x m2 = -1
m2 = -1/2
Now, using one point form formula,
y - y1 = m(x - x1)
or, y - 3 = -1/2( x - (-8))
or, y-3 = -1/2(x + 8)
or, y = -1/2x - 4 + 3
or, y = -1/2x - 1
This is the required equation.
