Q. A line with a slope of −4 passes through the points (−1,−6) and (0,p). What is the value of p?
Given Slope and Point: We are given the slope of the line and a point on the line. We can use the slope formula to find the value of p. The slope formula is x2−x1y2−y1=slope, where (x1,y1) and (x2,y2) are points on the line.
Apply Slope Formula: We know the slope is −4, and we have the points (−1,−6) and (0,p). Let's plug these into the slope formula: −1−0−6−p=−4.
Simplify Equation: Simplify the denominator to get (−6−p)/−1=−4.
Isolate Term with p: Multiply both sides by −1 to isolate the term with p: 6+p=4.
Solve for p: Subtract 6 from both sides to solve for p: p=4−6.
Calculate p Value: Calculate the value of p: p=−2.
