Full solution

Q. What is the slope of a line that passes through the points (3,5)(-3,-5) and (1,7)(1,7) in the xyxy-plane
  1. Find change in y: Find the change in y: 7(5)7 - (-5)
  2. Calculate: Calculate: 7+5=127 + 5 = 12
  3. Find change in x: Find the change in x: 1(3)1 - (-3)
  4. Calculate: Calculate: 1+3=41 + 3 = 4
  5. Slope formula: Slope formula: ΔyΔx=124\frac{\Delta y}{\Delta x} = \frac{12}{4}
  6. Simplify: Simplify: 124=3\frac{12}{4} = 3
