For each set of data provided below,

  • Decide which form of the line would be the easiest to build from the available information.

  • Write a definition of the linear model in that form.

  • Translate the definition into Pyret notation.

1

scatterplot with a slope of about -0.5 and a y-intercept of -10

Which Form is easiest? slope-intercept, point-slope, or standard form?

Equation:

fun f(x) : end

2

scatterplot with two identifiable points (42,300) and (57,375)

Which Form is easiest? slope-intercept, point-slope, or standard form?

Equation:

fun f(x) : end

3

scatterplot with the points (0,950) and (130,0) identified amidst a point cloud that is sloping down and to the righr

Which Form is easiest? slope-intercept, point-slope, or standard form?

Equation:

fun f(x) : end
