Q. What is the slope of a line that passes through the points (−3,−5) and (1,7) in the xy plane?Choose 1 answer:(A) 6(B) 3(C) 21(D) −1
Step 1: Slope formula: To find the slope of the line passing through two points, we use the slope formula: slope (m) = x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points.
Step 2: Substitute given points: Substitute the given points (−3,−5) as (x1,y1) and (1,7) as (x2,y2) into the slope formula.m=1−(−3)7−(−5)
Step 3: Simplify numerator and denominator: Simplify the numerator and the denominator.m = (7+5)/(1+3)m = 12/4
