Q. A line with a slope of −4 passes through the points (0,s) and (−1,−1). What is the value of s?
Slope Formula: The slope of a line passing through two points (x1,y1) and (x2,y2) is given by the formula:slope = x2−x1y2−y1We know the slope is −4, and we have the points (0,s) and (−1,−1). Let's plug these values into the slope formula.
Calculate Slope: Using the slope formula with our points:−4=0−(−1)s−(−1)−4=1s+1Now we need to solve for s.
Isolate s: Multiply both sides of the equation by 1 to isolate s on one side:−4×1=(s+1)−4=s+1Now we subtract 1 from both sides to solve for s.
Solve for s: Subtracting 1 from both sides gives us:−4−1=s−5=sSo, the value of s is −5.
