Q. A line with a slope of −4 passes through the points (7,8) and (8,g). What is the value of g?g=___
Identify formula for slope: Identify the formula for the slope between two points.The slope formula is (y2−y1)/(x2−x1). Here, (x1,y1)=(7,8) and (x2,y2)=(8,g).
Substitute known values: Substitute the known values into the slope formula.Slope = −4, so:−4=8−7g−8
Solve for g: Solve for g.−4=g−8g=−4+8g=4
