Using linear function concepts, it is found that the statement that accurately describes the procedure to find the slope and the y-intercept is given by:
To find the slope, use two ordered pairs on the line and substitute into the equation . To find the y-intercept, begin at the origin and move vertically to the graphed line.
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Given two points and
, the slope is given by <u>change in y divided by change in x</u>, hence:
The y-intercept is the value of y(vertical axis) when x = 0, hence we begin at the origin and move vertically to the graphed line.
