Question

5. Part A: Show another way to find the slope of the line that passes through the points listed in the table. Your way must be different from Avery's method.
. Part B: Justify why Avery's "divide y by x" method will not work to find the slope of every line and given an example (using a table, equation, or graph) in your justification

Answer 1

Answer:

The slope-intercept form

• y = mx + b

Here m is the slope and b is y-intercept

When b= 0

• y = mx

and

• m = y/x

In this case Avery's method works

When b≠0

• m = (y -b)/x

In this case Avery's method brings wrong outcome
