Write the fraction like this: 
1 \frac{1}{4}+ 2\frac{1}{2} =  \frac{1\cdot4+1}{4} +  \frac{2\cdot2+1}{2} =  \frac{5}{4}+ \frac{5}{2}  =  \frac{5}{4}  + \frac{5\cdot2}{2\cdot2}=  \frac{5+10}{4}  =\boxed{ \frac{15}{4} }

AfilCa [17]
The easiest way is to graph it based upon the slope (m) and y-intercept (b), in the standard slope-intercept form: y = m (x) + b.
The line above intercepts the y-axis at y = -2, which is b. The slope (m) = rise/run = (y2-y1)/(x2-x1 ); so for the point (-4, 2) to (-6, 4) is:
(4-2)/(-6--4) = 2/(-6+4) = 2/-2 = -1.
So one form of the equation would be:
y = -1x - 2
Now the other form of an equation is point-slope: y-k = m (x-h), where the point is at (h, k)
and if we pick -5 for x (bc 5 it listed in 3 of the answers), the y at x=-5 looks like around +3
so we get: y-k = -1 (x--5)...
y-3 = -(x+5)... therefore D) is the correct answer:
