Answer:
2a - b = 5
Step-by-step explanation:
4a - 2b = 10
take out the highest common factor of the left side
2(2a - b) = 10
divide both sides by two
2a - b = 10/2
2a - b = 5
Isosceles =there are 2 =sides
scalene no sides are the same
y = 
x + 5
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, 16 ) and (x₂, y₂ ) = (0, 5 )
m = 
= 
=
the y-intercept = (0, 5 ) ⇒ c = 5
y = x + 5 ← in slope-intercept form
