Answer:
(a) y = x/3 -1
Explanation:
You want the equation of the line graphed showing points (3, 0) and (6, 1).
Slope
The slope of the line is its "rise" divided by its "run." Here, the points are 3 units apart horizontally, and 1 unit vertically, with the line going up to the right. That means ...
slope = rise/run = +1/+3 = 1/3
Slope-intercept equation
The slope-intercept form of the equation for a line is ...
y = mx +b . . . . line with slope m and y-intercept b
The slope of 1/3 means the coefficient of x will be 1/3. There is only one answer choice like that:
y = x/3 -1
