Step-by-step explanation:

For a straight line for example,

Take any two points from the line and find the slope,

it will be the same value for any 2 points chosen

So throughout the graph, the slope/rate of change is not changing

That is

Throughout the graph rate of change/slope is constant

Answers

2x + 8y = 17
10x + 3y = 11

We need to solve the system of equations.

x = pencils
y = notebooks

If we solve by graphing, we get the answer:

One pencil costs 0.50 dollars
One notebook costs 2.00 dollars

55/100 in simplest form

Answers

(55)/(100) = (11* 5)/(20* 5) = \huge{\boxed{(11)/(20)}}
