Q. The points (−3,2) and (−2,r) fall on a line with a slope of −6. What is the value of r?r=___
Identify slope formula: Identify the formula for slope between two points.The slope formula is (y2−y1)/(x2−x1), where (x1,y1) and (x2,y2) are the coordinates of the two points.
Substitute points and slope: Substitute the given points and slope into the slope formula.Using points (−3,2) as (x1,y1) and (−2,r) as (x2,y2), and slope = −6:(−6)=(−2+3)(r−2)
Solve for r: Solve for r.−6=r−2r=−6+2r=−4
