Correct description of the given inequality will be, A solid line with y-intercept (-4) and slope 7. The graph will be shaded above the line.
Slope form of the line is given by equation,
y = mx + b
Where 'm' = Slope of the line
b = y-intercept
For a line having equation,
y = 7x - 4
Slope = 7
y-intercept = -4
If the line is an inequality, properties of the inequality will be defined by,
- If the line is having a sign equal to (=), graph of the line will be a solid line.
- If the solid line has a sign of greater than (>), solution set (shaded region) of the inequality will be above the line.
- If the line has a sign of less than (<), solution set of the inequality will be below the line.
By these properties,
inequality y ≥ 7x - 4 will show,
- A solid line with slope 7 and y-intercept as (-4).
- Shaded area will be above the solid line.
Therefore, the graph will be a solid line with y-intercept (-4) and slope 7. The graph will be shaded above the line.

Answer:
The correct option is B
B) The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line.
Step-by-step explanation:
The given equation is
y ≥ 7x - 4
Consider only the equality sign:
y = 7x-4
or
y = 7x + (-4)
The general form of any linear equation is given by:
y = mx + c
By comparing, we can see that:
m = slope = 7
Secondly consider the equation
y ≥ 7x - 4
We know that generally for the signs "equal to and greater/smaller than", we use a solid line, and for the signs "greater/smaller than", we use a dashed line.
Hence, to graph this equation we'll use a solid line.
Thirdly, find y intercept by putting x=0
y = 7(0) - 4
y = -4
The correct option is B

Rounding 62.8 to the nearest square root, the result would be 63 square feet.
To round 62.8 to the nearest squareroot, you would look at the decimal part of the number.
If the decimal part is less than 0.5, you would round down to the nearest whole number.
If the decimal part is 0.5 or greater, you would round up to the nearest whole number.
In this case, the decimal part of 62.8 is 0.8, which is greater than 0.5. Therefore, you would round up to the nearest whole number.
Rounding 62.8 to the nearest square foot, the result would be 63 square feet.

add the 2 equations together
2x+x+y-y=-8-4
3x=-12
divide by 3
x=-4
subsitute
-4-y=-4
addd 4 to both sdies
-y=0
the solution is (x,y) (-4,0) or D
I have decided to use Elimination by Addition.
Add the two equations together
3x = -12
Divide both sides by 3
x = -4
Substitute -4 for x in the second equation.
-4 - y = -4
Add 4 to both sides
-y = 0
y = 0
Check
2(-4) + 0 = -8
-8 = -8 This checks.
-4 - 0 = -4
-4 = -4 This also checks.
The solution set for this system is as follows:
S = {(-4,0)}
That would be option D.
