Write an equation of the line that passes through the points (1, 1) and (7, 4). y = 2x - 10 y = 2x - 1 y = (½)x 5 y = (½)x (½)

(1,1)(7,4)
slope(m) = (4-1) / (7-1) = 3/6 = 1/2

y = mx + b
slope(m) = 1/2
(1,1)...x = 1 and y = 1
now we sub...we r looking for b, the y int
1 = 1/2(1) + b
1 = 1/2 + b
1 - 1/2 = b
2/2 - 1/2 = b
1/2 = b

equation in slope intercept form : y = 1/2x + 1/2

Multiplication property of zero
