 Question 431239: please help..! Find the slope-intercept form for the equation of the line which passes through the point (–1, 3) and has a slope of –2. --- Find the slope-intercept form for the equation of the line which passes through the point (–3, 2) and the origin Found 2 solutions by rfer, stanbon:Answer by rfer(12662)   (Show Source): You can put this solution on YOUR website!y=mx+b 3=-2*-1+b 3=2+b b=1 -------- y=-2x+1 Answer by stanbon(57361)   (Show Source): You can put this solution on YOUR website!Find the slope-intercept form for the equation of the line which passes through the point (–1, 3) and has a slope of –2. --- Form: y = mx+b You have y = 3 when x = -1 and you have m = -2 Solve for "b"; 3 = -2*3+b 3 = -6+b b = 9 --- Equation: y = -2x+9 ================= --- Find the slope-intercept form for the equation of the line which passes through the point (–3, 2) and the origin --- You have y = 0 when x = 0 You have slope = (2-0)/(-3-0) = -2/3 ----- Solve for "b": y = mx + b 0 = (-2/3)*0 + b b = 0 ---- Y = (-2/3)x ================== Cheers, Stan H. ====================
