Question

Set-up a data table for the points of a linear relationship given below. Determine the slope of the line passing through the points as well as the equation of the line in slope-intercept form.

(x1, y1) = (-12, -44)
(x2, y2) = (4, 20)
(x3, y3) = (8, 36)


Hint: Calculate slope. Use the point-slope form an equation of a line, (y - y1) = m(x - x1), then convert point-slope form to slope-intercept form.

The slope of the line is .

The equation of the line in slope-intercept form is y = x + .
