Q. What is the slope of a line that passes through the points (3,5) (-3,-5) and (1,7) (1,7) in the xy x y plane?\newlineChoose 11 answer:\newline(A) 66\newline(B) 33\newline(C) 12 \frac{1}{2} \newline(D) 1-1
  1. Step 11: Slope formula: To find the slope of the line passing through two points, we use the slope formula: slope (m) = y2y1x2x1\frac{y_2 - y_1}{x_2 - x_1}, where (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are the coordinates of the two points.
  2. Step 22: Substitute given points: Substitute the given points (3,5)(-3, -5) as (x1,y1)(x_1, y_1) and (1,7)(1, 7) as (x2,y2)(x_2, y_2) into the slope formula.\newlinem=7(5)1(3)m = \frac{7 - (-5)}{1 - (-3)}
  3. Step 33: Simplify numerator and denominator: Simplify the numerator and the denominator.\newlinem = (7+5)/(1+3)(7 + 5) / (1 + 3)\newlinem = 12/412 / 4
  4. Step 44: Calculate simplified slope: Calculate the simplified slope.\newlinem = 124\frac{12}{4}\newlinem = 33
