Q. A line with a slope of 4-4 passes through the points (0,s)(0,s) and (1,1)(-1,-1). What is the value of ss?
  1. Slope Formula: The slope of a line passing through two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is given by the formula:\newlineslope = y2y1x2x1\frac{y_2 - y_1}{x_2 - x_1}\newlineWe know the slope is 4-4, and we have the points (0,s)(0, s) and (1,1)(-1, -1). Let's plug these values into the slope formula.
  2. Calculate Slope: Using the slope formula with our points:\newline4=s(1)0(1)-4 = \frac{s - (-1)}{0 - (-1)}\newline4=s+11-4 = \frac{s + 1}{1}\newlineNow we need to solve for ss.
  3. Isolate ss: Multiply both sides of the equation by 11 to isolate ss on one side:\newline4×1=(s+1)-4 \times 1 = (s + 1)\newline4=s+1-4 = s + 1\newlineNow we subtract 11 from both sides to solve for ss.
  4. Solve for ss: Subtracting 11 from both sides gives us:\newline41=s-4 - 1 = s\newline5=s-5 = s\newlineSo, the value of ss is 5-5.
