Q. What is the slope of the line through (−2,−6) and (2,2)?Choose 1 answer:(A) 21(B) −2(C) 2(D) −21
Identify slope formula: Identify the slope formula.The slope of a line is calculated by the change in y-coordinates divided by the change in x-coordinates between two points.Slope formula: (y2−y1)/(x2−x1)
Substitute given points: Substitute the given points into the slope formula.We have the points (−2,−6) and (2,2). Let's denote (−2,−6) as (x1,y1) and (2,2) as (x2,y2).Slope: (2−(−6))/(2−(−2))
Calculate change in y-coordinates: Calculate the change in y-coordinates.Change in y: 2−(−6) which simplifies to 2+6=8
Calculate change in x-coordinates: Calculate the change in x-coordinates.Change in x: 2−(−2) which simplifies to 2+2=4
Calculate slope using changes in y and x: Calculate the slope using the changes in y and x.Slope: 48
Simplify fraction to find slope: Simplify the fraction to find the slope. 48 simplifies to 2
Match calculated slope to answer choice: Match the calculated slope to the correct answer choice.The calculated slope is 2, which corresponds to answer choice (C) 2.
