Which of the points listed is the same distance from the x-axis as the point (7, 8.75)?
2 answers:
The complete question in the attached figure
we know that
The distance of the point (7, 8.75) to the x-axis (the horizontal line) is 8.75
<span>then
case </span>A) (-7, 5.25)---------> is not correct ( the distance to the x-axis is 5.25)
case B) (8.75, 6)---------> is not correct ( the distance to the x-axis is 6)
case C) (6, -8.75)---------> is correct ( the distance to the x-axis is 8.75)
the answer is the option C) (6, -8.75)

Answer:
Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5
Subtract x from both sides
Divide both sides by 3
The slope of the line is the coefficient of x
Slope =
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of
Having calculated the slope, next is to calculate the equation of the line using the following formula;
Where m is the slope; m = ;
Substitute these values in the formula above; the formula becomes
Cross Multiply
Open brackets
Add x to both sides
Add 6 to both sides
Multipby both sides by -3
Comparing the above to Ax + By = 3
