- What
is the slope of the line between (-1, -3) and (3,5) ? 8/4 = 2
- Graph
the points. What is the y-intercept? -1
- What
is the equation of this line? y = 2x - 1
- Use
point-slope form to find the equation of the line between (-3, 2)
and (6, 7)
m = (7-2)/(6--3) = 5/9.
y - 7 = (5/9)(x - 6)
y - 7 = .55x - 3.33
+7
+7
y = .55x + 3.66 or y = (5/9)x + 11/3
