A
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, - 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = =

The value of n in the given equation is -2.6
Step-by-step explanation:
Given,
10 =
To find the value of n
10 =
or, 10(3n+8) = 2 [ by cross multiplication]
or, 30n + 80 = 2
or, 30n = 2-80 [ taking the constant values in one side]
or, 30n = -78
or, n =
or, n = -2.6
