Q. A line with a slope of 8 passes through the points (−7,c) and (−8,−6). What is the value of c?c = ____
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 8, and we have the points (−7,c) and (−8,−6). Let's plug these into the slope formula:8=−7−(−8)c−(−6)
Simplify equation and solve: Simplify the equation and solve for c.8=−7+8c+68=1c+6Now, multiply both sides by 1 to isolate c+6 on one side:8×1=c+68=c+6
Subtract to find c: Subtract 6 from both sides to solve for c.8−6=c2=c
