The slope- intercept equation is
y = mx + b
Where, m = slope and b = intercept
slope = 1/7
We are given a point on the line as (7, 0)
The slope - intercept equation for a given point is
(y - y1) = m(x - x1)
y1 = 0 and x1 = 7
(y - 0) = 1/7(x - 7)
Open the parentheses
y = 1/7 * x - 1/7 x 7
y = 1/7x - 1
The answer is y = 1/7x - 1
