 Question 61236: write as an equation and then solve 15 is 3 less than half a number Im thinking of a number. Ill subtract 7 and then multiply the result by 3, I get 18. What was the original number? write in standard form: y=3x-1 whats the slope of (-5,2) and (1,4) write the slope-intercept form of 3x+y=4 find slope of 3x+y=4Answer by DJ_Sammie(24)   (Show Source): You can put this solution on YOUR website!let n = the number 15=1/2n-3 let n = the number (n-7)*3=18 n=6 2-4/-5-1=m m=slope so -2/-6=m 1/3=m 3x+y=4 -3x -3x y=-3x+4 3x+y=4 -3x -3x y=-3x+4 y=mx+b m=slope so the slope is -3
