Which of the following points lies on the x-axis?
Compute the slope (mm) of the line through the points (−2,5)(−2, 5) and (4,−1)(4, −1).
Write the equation in slope-intercept form for the line with slope 44 that passes through (12,−34)\(\left\)(\(\frac\)12,-\(\frac\)34\(\right\)).
A small greenhouse's temperature increases linearly over four days. At day 2 the temperature was 14°C and at day 6 it was 26°C. (i) Compute the slope (rate of temperature change per day). (ii) Write the temperature in point-slope form using the day-2 data, and (iii) convert to slope-intercept form.
Which of the following best describes when point-slope form is preferable over slope-intercept form?
