Answer:

15 1/3

Step-by-step explanation:

a = 7

b = -4

plugging the above value in |2a| - b/ 3

|2a| - b/ 3 = |2*7| - (-4)/ 3

|x| is modulus function so whatever be the value of be it negative or positive, modulus of this x is positive x

=> |14| + 4/ 3 = 14 + 4/3

=> (14*3 + 4)/3 = (42+4)/3 = 46/3 = 15 1/3

|2a| - b/ 3 = 15 1/3 when a = 7 and b = -4

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.
