Hi, 
Using the general slope=intercept form for an equation of a line:
y = mx + b where m is the slope and b the y-intercept
y = (-3/4)x + b  Using ordered pair(8,-4) to solve for b
-4 = (-3/4)*8 + b
-4 = -6 + b
2 = b
equation of the line is:
y = (-3/4)*x + 2
x = -4 
y = (-3/4)*-4 + 2  = 5

y = (-3/4)*x + 2
y = &#8722;1
-1 = (-3/4)*x + 2
-3 = (-3/4)*x 
4 = x
