I don't know what the 21 means ?? -------------- Do it like this one. ------------------------ The slope, m = -3 ---------------- Use y = mx + b and the point (1,2) to find b. 2 = (1/3)*1 + b b = 5/3 The equation is y = (1/3)x + 5/3 (slope-intercept form) x - 3y = -5 (standard form) ------------------------ For further assistance, or to check your work, email me via the thank you note. Answer by richwmiller(10283)   (Show Source): You can put this solution on YOUR website!You almost had it but this (3,0)=21 means nothing. y=mx+b 0=3*-7+b 21=b y=-7x+21 Perhaps you meant that the y intercept (b) =21 y=-7x+21 is in slope intercept form Standard form is ax+by+c=0 subtract y from both sides 0=-7x-y+21 -7x-y+21=0
