Find an equation of the line that passes through the given points. (4,5)and (12,8)
.
first, find the slope:
(y2 - y1)/(x2 - x1)
(8 - 5)/(12 - 4)
3/8
.
using the slope and one of the two points (4,5) plug it into the "point-slope" form:
y - y1 = m(x - x1)
y - 5 = (3/8)(x - 4)
y - 5 = (3/8)x - 3/2
y = (3/8)x - 3/2 + 5
y = (3/8)x - 3/2 + 10/2
y = (3/8)x + 7/2
