To find the equation of the line, first find the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
m = (5 - (-8)) / (8 - 4)
m = 13 / 4
The slope is 13/4. Next, use the point-slope form of the equation of a line:
(y - y1) = m(x - x1)
Using the point (4, -8):
(y - (-8)) = (13/4)(x - 4)
y + 8 = (13/4)(x - 4)
Now simplify the equation:
y + 8 = (13/4)x - (13/4) * 4
y + 8 = (13/4)x - 13
y = (13/4)x - 13 - 8
y = (13/4)x - 21
So the equation of the line is y = (13/4)x - 21.
complete the equation of the line through (4,-8) and (8,5).
