What is the slope of a line that is perpendicular to the line whose equation is ax+by=c?
Oksi-84 [34.3K]

The perpendicular line will have a slope of b/a.

To find this, we first have to solve our equation for slope intercept form.

ax + by = c ----> subtract ax

by = -ax + c ----> divide by b

y = -a/bx + c/b.

So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.

4. Hightop Roofing was $3765 in the "red" (owed creditors this amount) at the end of
gulaghasi [49]

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.

Step-by-step explanation:

Amount owed at the end of June = $3765

Amount owed at the end of December = $8765

As Hightop Roofing owed creditors the amount, therefore, we will consider the amount as negative, therefore,

Amount in June = -3765

Amount in December = -8765

To see the difference, we will subtract the amount owed in June from the amount owed in December.

Difference=(-8765)-(-3765)\\Difference=-8765+3765\\Difference=-5000

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.
