What I the slope of each line? Y=1/2 x - 4
y= 2x -3

1/2

2

Step-by-step explanation:

y = 1/2x - 4 (the slope for this line is 1/2)

y = 2x - 3 (the slope for this line is 2)

Hope this helps!

Step-by-step explanation:

the slope is always the factor of x (a) in the line equation.

either in

y = ax + b

or in

y - y1 = a(x - x1) with (x1, y1) being a point on the line.

it represents the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

and so, the slopes of the 2 lines are

1/2

2

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
