Q. A line with a slope of −10 passes through the points (4,10) and (6,d). What is the value of d?d = ____
Understand slope concept: Understand the concept of slope. The slope of a line is the ratio of the change in the y-coordinate to the change in the x-coordinate between two points on the line. The formula for slope (m) when given two points ((x1,y1) and (x2,y2)) is: m=x2−x1y2−y1
Apply slope formula: Apply the slope formula to the given points and slope.We know the slope m is −10, and we have the points (4,10) and (6,d). Let's plug these values into the slope formula:−10=6−4d−10
Solve for d: Solve for d.Now we need to solve the equation for d:−10=2(d−10)Multiply both sides by 2 to isolate (d−10):−10×2=d−10−20=d−10Now, add 10 to both sides to solve for d:−20+10=d−10=d
