This is a simple multiplication problem, and the best thing to do may be to split up the answer. I would split the 8.5 into 8 and 0.5 8*4.16= 33.28 0.5*4.16= 2.08 2.08+33.28= 35.36 Therefore, the answer that you're looking for is A Hope this helps :)
Turn it into slope-intercept form. 2y = -x + 14 y = -x/2 + 7 The slope is -1/2. Perpendicular lines have slopes that are opposite reciprocal, so the slope of the perpendicular line is 2.
