Q. What is the slope of the line through (−7,−8) and (0,4)?Choose 1 answer:(A) −712(B) 712(C) 127(D) −127
Identify slope formula: Identify the slope formula.The slope of a line passing through two points (x1,y1) and (x2,y2) is given by the formula:Slope = x2−x1y2−y1
Substitute given points: Substitute the given points into the slope formula.We have the points (−7,−8) and (0,4). Let's assign these values to the formula:x1=−7, y1=−8, x2=0, y2=4.Slope = 0−(−7)4−(−8)
Calculate change in y: Calculate the change in y (rise).Change in y=y2−y1=4−(−8)=4+8=12
Calculate change in x: Calculate the change in x (run). Change in x = x2−x1=0−(−7)=0+7=7
Calculate slope: Calculate the slope using the changes in y and x.Slope = Change in xChange in y=712
Determine correct answer: Determine the correct answer from the given options.The calculated slope is 712, which corresponds to option (B).
