Write the equation of the line from the graph given

STEP 1: Recall how to find the slope from the points given
http://cls.syr.edu/mathtuneup/grapha/Unit4/Unit4a.html
Locating (0,8) and (-2,0) we find the slope of the line
slope of the line is \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
\frac{0-8}{-2-0}
=\frac{-8}{-2}
= 4
STEP 2: Recall on how to find the y-intercept

Locate the y-intercept on the graph.
The y-intercept is where the line touches the y-axis and the value of x is 0.
So, the y-intercept is 8
STEP 3: Recall the standard equation of a line
http://www.mathcentre.ac.uk/resources/uploaded/mc-ty-strtlines-2009-1.pdf
The standard equation of the line is y = mx + b
where m is the slope of the line and b is the y-intercept
Plugging in the values we get
y = 4 x + 8
