Answer:
that is too....much? it's n = 5
Step-by-step explanation:
60/12 = 12n/12
5 = n
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
Answer:
4) 7a + 11b
5) i'm not sure
6) 3 (n = 3)
7) i can't see the last ones, but i know that y = 6
i hope this helps
sorry i can't help more :(
Have a great day!
Answer:
There is no slope. 
Step-by-step explanation:

(2, 2) and (4,2) makes a horizontal line. All horizontal lines on a graph have no slope.
Answer:
4
Step-by-step explanation:
the smaller triangle is the larger triangle divided by 4 so 16÷4 is 4.
