The slope of the line is \[\frac{3 - (-4)}{-1 - 7} = \frac{7}{-8} = -\frac{7}{8}\]
Using point-slope form with the point (7, –4):
\[y - (-4) = -\frac{7}{8}(x - 7)\]
\[y + 4 = -\frac{7}{8}x + \frac{49}{8}\]
Slope-intercept form of the line:
\[y = -\frac{7}{8}x + \frac{49}{8}\]
Write the equation of the line that passes through the points (7, –4) and (–1, 3), first in point-slope form, and then in slope-intercept form.
The slope of the line is ____.
When the point (7, –4) is used, the point-slope form of the line is __________.
The slope-intercept form of the line is ________.
