A mixture of purple paint contains 6 teaspoons of red paint and 15 of blue to make the same shade of purple paint using 35 teaspoons of blue paint how much red do you need ?

The slop of line perpendicular to line y = x - 2 is     ( - 3)  

Step-by-step explanation:

Given Line equation as ,

y = x - 2

The equation of line is y = mx + c

Slop of this line (m1) =

Now second line with slop (m2) is perpendicular to line first , then

(m1) × (m2) = - 1

So, (m2) =

Or , (m2) =

∴     (m2) = - 3

Hence the slop of line perpendicular to line y = x - 2 is      ( - 3)      Answer
