Write an equation in slope-intercept form of the line through point (6, 7) with a slope of -2

Start off by putting the equation in point slope form (y-y1=m(x-x1) and substitute in the information you have so far.
y - 7 = -2(x - 6)
Distribute the -2(x-6)
y - 7 = -2x + 12
Add the 7
y = -2x + 19 is your final answer!

The answer to that question your asking is 64

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
