C

Standard: y = mx+b  
          m is the slope
          b is the y-intercept (the value of y when x=0)

anonymous · Answer

where m=(y2-y1)\(x2-x1)=(10-3)\(2-0)=7\2
,therefore :y=7\2x+10 ,but since there is no choise =that,so we will take a negative sign as a common so it will be -(7\2x-10) which is (A)
