is the equation best represents the line.
Solution:
Take any two points on the line.
Let the points be (0, –4) and (4, 7).

General form of equation of a line is y = mx + c
where m is the slope and c is the y-intercept of the line.
<em>y-intercept is the point which line crosses at y-axis.</em>
In the given line, y-intercept is 4.
c = 4
Slope of the line:



Equation of the line:
y = mx + c

Hence
is the equation best represents the line.
Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
Do 48/6, then multiply the answer by $5
