The equation of a line that goes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so, given the point (-2,8)
x1=-2
y1=8
y-8=m(x-(-2))
y-8=m(x+2)
the equation is y-8=m(x+2) where m is the slope
or you could rewrite it to get y=mx+2m+8
The area of a triangle is always:
A=bh/2 (base times the height divided by 2)
A=3x(2x)/2
A=6x^2/2
A=3x^2
...
y = 5/2x + 5 would be your equation
