y = - x -
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 1 ) and (x₂, y₂ ) = (2, - 5 )
m = = = -
the partial equation is
y = - x + c
to find c substitute either of the 2 given points into the partial equation
using (- 6, 1 ), then
1 = + c ⇒ c = 1 - = -
y = - x - ← equation of line

Answer:
The answer is a= 15
Step-by-step explanation:
First, you multiply both sides by 5. 5*3 = 15 and a/5*5 = a, since 5 and 5 cancels out each other. This is optional, then you flip the equation to get a= 15. Hope this helps.
